Product details
Overview
TPS7A6150QKVURQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-grade LDO regulator delivering fixed 5-V output at up to 300 mA, with 25-µA quiescent current, 7–40-V input range, and integrated enable and open-drain reset functionality. It operates in automotive head units and instrument clusters where cold-crank resilience and low-power sleep mode are critical.
For engineers reviewing the TPS7A6150QKVURQ1 datasheet, TPS7A6150QKVURQ1 pinout, TPS7A6150QKVURQ1 application, or TPS7A6150QKVURQ1 equivalent, key selection criteria include its 5-V fixed output, TO-252-5 (KVU) thermally enhanced package, 250-µs internal reset delay, enable-controlled startup, and 300-mA output capability under 150°C junction temperature.
Technical Context
The TPS7A6150QKVURQ1 implements a PMOS pass transistor architecture enabling ultra-low dropout (300 mV at 150 mA) and stable operation with ceramic output capacitors ≥1 µF. Its integrated charge pump enables regulation down to 7 V input while maintaining low quiescent current via automatic switching between high-efficiency (25 µA) and higher-current (250 µA) modes based on load and VIN.
It features a dedicated ENABLE pin tolerant to 40 V, an open-drain nRST output with 93% VOUT threshold detection and 5.5-µs deglitching, and built-in fault protection including thermal shutdown (165°C trip), overcurrent limiting (350–1000 mA), and undervoltage lockout (3.16 V turn-off).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5 V ±2%; maintains regulation across –40°C to 150°C ambient and 10–300 mA load. |
| Input Voltage Range | 7 V to 40 V; withstands 45-V transients for 480 ms - supports automotive battery systems including cold-crank (down to 4 V for ≤130 ms). |
| Quiescent Current | 25 µA typical at light load; drops to <3 µA in shutdown when ENABLE <0.8 V - enables always-on ECU modules. |
| Dropout Voltage | 300 mV at 150 mA; ensures stable 5-V output even at VIN = 5.3 V - eliminates need for pre-regulation in 6–7 V brownout conditions. |
| Reset Delay | 250 µs typical, internally fixed (no external capacitor required); provides deterministic power-on sequencing for microcontrollers. |
| Thermal Protection | 165°C shutdown with 10°C hysteresis; prevents latch-up during sustained overload or poor PCB heatsinking. |
| ESD Rating | ±4000 V HBM (KVU package); meets AEC-Q100 stress requirements for automotive assembly environments. |
Pinout & Package
TPS7A6150QKVURQ1 uses the TO-252-5 (KVU) thermally enhanced surface-mount package (6.10 mm × 6.60 mm body, exposed thermal pad). The 5-pin configuration supports high-current operation and efficient PCB heat dissipation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN | Unregulated input supply | Accepts 7–40 V; requires local 1-µF ceramic bypass to GND; handles 45-V transients per ISO 7637-2. |
| nRST | Open-drain reset output | Pulled low when VOUT <93% of 5 V; requires external pullup to VOUT or system rail; 5.5-µs deglitch prevents false resets. |
| GND | Signal and power ground reference | Common return for VIN, VOUT, ENABLE, and nRST; must be connected to exposed thermal pad for thermal performance. |
| ENABLE | High-voltage enable control | Active-high logic input (VIH ≥2.5 V); tolerates up to 40 V; internal pulldown holds device OFF if left floating. |
| VOUT | Regulated 5-V output | Delivers up to 300 mA; requires ≥1-µF low-ESR ceramic capacitor to GND for stability; tracks VIN below dropout. |
Key Features
| Feature | Design Value |
|---|---|
| Enable-controlled startup | Allows precise system-level power sequencing; eliminates uncontrolled turn-on during battery connection. |
| Integrated power-on reset | 250-µs fixed delay ensures MCU boot only after VOUT reaches 4.65 V and remains stable - no external timing components needed. |
| Low-input-voltage tracking | Below dropout, VOUT = VIN – (IOUT × RSW); enables operation down to ~4 V without external boost - reduces BOM count in cold-crank designs. |
| Thermal shutdown with hysteresis | 165°C trip + 10°C recovery margin prevents thermal cycling instability during sustained 300-mA loads on minimal copper. |
| AEC-Q100 Grade 1 qualification | Validated for –40°C to 125°C ambient (–40°C to 150°C junction); includes HTOL, temperature cycling, and ESD testing per automotive standards. |
Applications
| Automotive Head Units | Hybrid Instrument Clusters |
|---|---|
Use Scenario: Powering infotainment SoCs and display controllers in 12-V vehicle architectures with frequent engine start-stop cycles. IC Role / Device Role / Timing Role: Primary 5-V LDO supplying core logic rails; provides clean, sequenced power with reset assertion during cranking dips. Use Value: Maintains regulation during 6-V cold-crank events via low-VIN tracking, eliminating need for external boost converter and reducing board space by 35%. |
Use Scenario: Supplying digital gauges, CAN transceivers, and backlight drivers in multi-zone cluster ECUs with strict EMC and thermal constraints. IC Role / Device Role / Timing Role: System supervisor LDO with integrated reset; coordinates MCU boot and peripheral initialization after ignition-on. Use Value: 25-µA quiescent current extends battery drain time >1000 hours in sleep mode; 45-V transient tolerance avoids TVS diodes on input. |
| Center Information Displays | ADAS Domain Controllers (Auxiliary Rails) |
Use Scenario: Providing stable 5-V bias to touch controllers, camera interfaces, and audio codecs in large-format center-stack displays. IC Role / Device Role / Timing Role: Secondary regulated rail generator; ENABLE pin synchronized to display power tree for zero-crossing turn-on. Use Value: 300-mA output supports burst-mode LCD backlight drivers; PSRR >60 dB at 100 Hz suppresses alternator ripple noise. |
Use Scenario: Powering non-safety-critical auxiliary circuits (e.g., fan control, status LEDs, diagnostics UART) in ISO 26262-compliant ADAS ECUs. IC Role / Device Role / Timing Role: Fault-isolated auxiliary LDO; thermal shutdown and overcurrent protection prevent single-point failure propagation. Use Value: Integrated protection eliminates need for discrete current-limiting FETs and thermal sensors - reduces component count by 4 and layout area by 22 mm². |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS7B6750QKVURQ1 | Higher 45-V max input, lower 15-µA IQ, but no ENABLE pin; fixed 5-V only; same KVU package. | Lacks enable control - unsuitable for sequenced power trees; better for always-on sensor nodes. | Select when lowest possible quiescent current is primary, and enable control is unnecessary. |
| TLV73350PDBVR | 300-mA, 5-V fixed LDO with 60-µA IQ, 1.7–5.5-V input, SOT-23-5 package; no reset or automotive qualification. | Not AEC-Q100 qualified; lacks reset, thermal shutdown, and high-VIN capability - limited to non-automotive consumer use. | Select only for cost-sensitive, non-automotive applications where 40-V transients and Grade 1 operation are not required. |
Compared with TPS7B6750QKVURQ1, the TPS7A6150QKVURQ1 trades 35-µA higher quiescent current for essential enable control and identical reset functionality; versus TLV73350PDBVR, it adds full automotive qualification, 45-V transient robustness, and integrated fault protection - making it the only viable option for ASIL-B auxiliary rail designs.

FAQ
What is the maximum input voltage transient the TPS7A6150QKVURQ1 can withstand?
The TPS7A6150QKVURQ1 is rated for 45-V transients on the VIN pin for durations less than 480 ms, per its Absolute Maximum Ratings table. This capability supports compliance with ISO 7637-2 Pulse 1, 2a, 3a, and 3b test waveforms common in 12-V automotive systems. Operation above 40 V is not recommended for continuous use, and the device enters safe shutdown if junction temperature exceeds 165°C during sustained overvoltage.
Does the TPS7A6150QKVURQ1 require an external capacitor on the ENABLE pin?
No, the TPS7A6150QKVURQ1 does not require an external capacitor on the ENABLE pin. Its ENABLE input has an internal pulldown resistor and is designed for direct connection to a microcontroller GPIO or system power rail. The pin is high-voltage tolerant (up to 40 V), allowing direct tie to VIN for self-bias applications. Adding capacitance may slow enable timing and is not specified or recommended in the datasheet.
Can the reset delay of the TPS7A6150QKVURQ1 be adjusted externally?
No, the TPS7A6150QKVURQ1 has a fixed internal reset delay of 250 µs (typical), as confirmed in the Device Comparison Table and Functional Block Diagram section. Unlike the TPS7A60-Q1 family, the TPS7A61-Q1 series - including TPS7A6150QKVURQ1 - omits the RDELAY pin and programmable delay circuitry. Any attempt to add external timing components will not alter the reset behavior.
What is the minimum output capacitor value required for stability with the TPS7A6150QKVURQ1?
The TPS7A6150QKVURQ1 requires a minimum 1-µF ceramic output capacitor with low ESR (≤100 mΩ) placed close to the VOUT and GND pins. This value is validated across temperature and load for phase margin >45°, as shown in Figure 13 (ESR Stability vs Load Current). Using smaller or higher-ESR capacitors risks oscillation, especially under dynamic load steps typical in automotive display and audio applications.
Is the TPS7A6150QKVURQ1 pin-compatible with other devices in the TPS7A6x-Q1 family?
The TPS7A6150QKVURQ1 shares the same TO-252-5 (KVU) package footprint and pinout with TPS7A6133QKVURQ1, but is not pin-compatible with TPS7A60-Q1 variants (e.g., TPS7A6050QKVURQ1), which substitute RDELAY for ENABLE on Pin 4. Swapping TPS7A60 and TPS7A61 devices requires PCB layout revision due to this functional pin reassignment - confirmed in the Pin Functions table and Device Comparison Table.
