Product details
Overview
TPS78230QDRVRQ1 from Texas Instruments is an automotive-grade, 3.0-V fixed-output, 150-mA ultra-low-quiescent-current LDO regulator in a 2-mm × 2-mm SON-6 package. It delivers 1 μA quiescent current, 130 mV dropout at 150 mA (25°C), ±4% output accuracy over load/line/temperature, and stable operation with only a 1-μF ceramic output capacitor - enabling use in battery-powered automotive microcontrollers and memory cards.
For engineers reviewing the TPS78230QDRVRQ1 datasheet, TPS78230QDRVRQ1 pinout, TPS78230QDRVRQ1 application, or TPS78230QDRVRQ1 equivalent, key selection criteria include ultra-low IQ for extended battery life, thermal shutdown and overcurrent protection for fault resilience, CMOS-compatible enable logic, and compatibility with TI MSP430 and similar ultra-low-power MCUs.
Technical Context
The TPS78230QDRVRQ1 uses a PMOS pass transistor architecture to achieve low dropout and maintain regulation down to VIN = VOUT + 130 mV at full load. Its internal EEPROM-programmed fixed 3.0-V output eliminates external feedback components and ensures factory-trimmed accuracy across –40°C to 125°C.
It integrates active pulldown circuitry that discharges the output within 500 μs during shutdown, supports 18 nA shutdown current, and features built-in thermal shutdown (trip at ~160°C, reset at ~140°C) and current limiting (~150–400 mA). All ground pins (GND on pins 3 and 5) must be connected, and the thermal pad is recommended to be grounded.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0 V ±4% over load/line/temperature - eliminates need for external resistive divider and ensures consistent rail for MCU I/O or sensor biasing. |
| Quiescent Current | 1 μA typical - enables multi-year operation from coin-cell batteries in always-on automotive modules like door controllers or tire pressure sensors. |
| Dropout Voltage | 130 mV at 150 mA (25°C); 175 mV at 150 mA (85°C) - allows regulation from 3.13 V input at room temp, critical for aging battery systems. |
| Output Capacitor | Stable with ≥1.0 μF ceramic (X5R/X7R) - reduces BOM count and PCB area vs. larger electrolytic or tantalum solutions. |
| Enable Threshold | Active-high EN: ON >1.2 V, OFF <0.4 V - directly interfaces with standard CMOS logic without level-shifting in automotive MCU GPIOs. |
| Protection Features | Thermal shutdown (160°C trip), overcurrent limit (~150 mA min), and active output pulldown - prevents latch-up and ensures safe recovery after fault events. |
| Operating Temp | –40°C to +125°C junction temperature - qualified per AEC-Q100 Grade 1 for under-hood and body-control module deployment. |
Pinout & Package
TPS78230QDRVRQ1 is housed in a thermally enhanced 2-mm × 2-mm SON-6 package (DRV) with exposed thermal pad. The package supports high-density automotive PCB layouts and requires grounding of all GND pins and the thermal pad for optimal thermal performance and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Regulated output | Delivers stable 3.0 V; requires ≥1.0 μF ceramic capacitor to GND for stability and transient response. |
| 2 - NC | No connection | Internally unconnected; must remain floating - no routing or soldering allowed. |
| 3 - GND | Ground reference | Primary ground return path; must be tied to system ground plane with low-impedance connection. |
| 4 - EN | Enable control | CMOS-compatible input; drives regulator ON/OFF; internal pull-down ensures default-off state if left unconnected. |
| 5 - GND | Ground reference | Secondary ground pin; must be connected to same ground net as Pin 3 to minimize noise coupling. |
| 6 - IN | Input supply | Accepts 2.2 V to 5.5 V; benefits from local 1-μF ceramic decoupling to reduce input ripple and improve PSRR. |
| Thermal Pad | Thermal & electrical ground | Exposed copper pad on bottom; recommended to connect to large ground plane via multiple vias for thermal dissipation and noise reduction. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low IQ | 1 μA quiescent current enables >10-year battery life in always-on automotive sensing nodes (e.g., occupancy detection). |
| Factory-programmed output | 3.0 V fixed output laser-trimmed in EEPROM - eliminates external resistor network and ensures ±4% accuracy across full automotive temperature range. |
| Miniaturized packaging | 2-mm × 2-mm SON-6 footprint saves >60% board area vs. SOT-23 alternatives - ideal for space-constrained modules like smart actuators. |
| Active output pulldown | Discharges VOUT to <5% of nominal within 500 μs at shutdown - prevents floating rails and unintended wake-up in downstream logic. |
| Robust protection suite | Integrated thermal shutdown, current limiting, and reverse-voltage body-diode management - reduces need for external protection components. |
Applications
| Automotive Body Control Module | Tire Pressure Monitoring System (TPMS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS78230DRVR | Non-automotive grade (no AEC-Q100 qualification); identical electrical specs and pinout. | Limited to industrial/commercial environments; not suitable for under-hood or safety-critical automotive functions. | Select when AEC-Q100 compliance is unnecessary and cost sensitivity is higher. |
| TPS7A0530PDBVR | Lower IQ (250 nA), smaller 1.5-mm × 1.5-mm X2SON-4 package, but only 200-mA max output and no thermal shutdown. | Better for ultra-long-life coin-cell devices (e.g., key fobs), but lacks fault protection needed in engine bay deployments. | Choose for space-constrained, non-safety-critical battery nodes where thermal robustness is secondary. |
Compared with TPS78230QDRVRQ1, TPS78230DRVR offers identical performance without automotive qualification, while TPS7A0530PDBVR trades protection and current capability for lower IQ and smaller size - making each suitable for distinct reliability and lifetime requirements.

FAQ
What is the maximum input voltage rating for TPS78230QDRVRQ1?
The absolute maximum input voltage for TPS78230QDRVRQ1 is +6.0 V. However, the recommended operating input voltage range is 2.2 V to 5.5 V per the datasheet's electrical characteristics table. Exceeding 5.5 V may cause permanent damage or degrade long-term reliability, especially under high-temperature conditions.
Does TPS78230QDRVRQ1 require an input capacitor for stability?
TPS78230QDRVRQ1 does not require an input capacitor for stability, but a 0.1-μF to 1.0-μF ceramic capacitor is strongly recommended near the IN pin to improve transient response, reduce input ripple, and enhance PSRR. This practice mitigates reactive source impedance and ensures robust operation in noisy automotive power environments.
Can TPS78230QDRVRQ1 be used with a 0.47-μF output capacitor?
No - TPS78230QDRVRQ1 is specified to be stable only with output capacitance ≥1.0 μF (ceramic, X5R/X7R type). Using 0.47 μF violates the minimum stability requirement and risks oscillation, poor transient response, or output voltage overshoot during load steps. Always use ≥1.0 μF with ESR <1.0 Ω.
How does the enable pin (EN) behave during power-up for TPS78230QDRVRQ1?
The EN pin of TPS78230QDRVRQ1 is active-high with CMOS-compatible thresholds: regulator turns ON when EN ≥1.2 V and enters shutdown when EN ≤0.4 V. During power-up, if EN is tied to VIN, startup occurs immediately once VIN exceeds ~2.2 V; startup time to 90% VOUT is typically 500 μs with 1-μF COUT.
Is the thermal pad of TPS78230QDRVRQ1 electrically connected internally?
Yes - the thermal pad of TPS78230QDRVRQ1 is internally connected to GND. The datasheet explicitly recommends grounding the thermal pad to improve thermal dissipation, reduce junction temperature rise, and lower output noise. Failure to connect it may result in thermal shutdown activation under moderate load or degraded PSRR performance.
