Product details
Overview
TPS76750QPWPRQ1 from Texas Instruments is an automotive-grade 5-V fixed-output low-dropout (LDO) voltage regulator with PMOS pass element, 230 mV dropout at 1 A, 85 µA typical quiescent current, ±2% output voltage tolerance over line/load/temperature, and integrated open-drain power-on reset with 200-ms delay. It powers microcontroller core logic in engine control units.
For engineers reviewing the TPS76750QPWPRQ1 datasheet, TPS76750QPWPRQ1 pinout, TPS76750QPWPRQ1 application, or TPS76750QPWPRQ1 equivalent, key selection criteria include dropout performance under 1-A load, thermal shutdown behavior at 150°C, RESET threshold hysteresis (0.5% VO), and compatibility with 10-µF low-ESR output capacitors for transient stability.
Technical Context
The TPS76750QPWPRQ1 uses a voltage-driven PMOS pass transistor to achieve load-independent quiescent current (85 µA typ, ≤125 µA max over −40°C to 125°C) and linear dropout voltage scaling (230 mV typ / 380 mV max at 1 A). Its internal 1.1834-V reference feeds a precision error amplifier that maintains output regulation within ±2% across input voltage (6.0–10 V), load (0–1 A), and temperature.
RESET functionality relies on an internal comparator monitoring regulated output voltage, asserting low when VO drops to 92–98% of nominal (i.e., 4.6–4.9 V for 5-V output), with 200-ms timeout and 0.5% hysteresis. The device operates in shutdown mode (EN = high), reducing quiescent current to 1 µA at TJ = 25°C and ≤10 µA over full temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 5.0 V ±2% (4.90–5.10 V over −40°C to 125°C, 0–1 A load) |
| Dropout Voltage | 230 mV typ / 380 mV max at 1 A (enables operation with VI ≥ 5.38 V) |
| Quiescent Current | 85 µA typ / 125 µA max (enables >10-year battery life in always-on automotive modules) |
| RESET Threshold | 92–98% VO with 0.5% hysteresis (asserts low at ~4.6–4.9 V, releases at ~4.925 V) |
| Thermal Shutdown | 150°C junction trip / 130°C hysteresis (prevents permanent damage during sustained overload) |
| Input Voltage Range | 6.0 V to 10 V (VI(min) = VO + VDO(max) = 5.38 V; VI(max) limited by absolute max rating of 13.5 V) |
| PSRR | 60 dB at 1 kHz (suppresses ripple from upstream switching converters) |
Pinout & Package
TPS76750QPWPRQ1 is housed in a 20-pin HTSSOP (PWP) package with PowerPAD™ thermal pad, rated for −40°C to 125°C ambient operation and qualified per AEC-Q100 for automotive use. The exposed thermal pad must be soldered to PCB copper for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 9, 10, 11, 12, 19, 20 | GND/HSINK | Ground return path and thermal heatsink connection; all pins tied internally to die substrate and exposed PowerPAD |
| 3 | GND | Dedicated regulator ground reference for feedback and control circuitry |
| 4, 8, 17, 18 | NC | No internal connection; must remain unconnected on PCB |
| 5 | EN | Enable input (TTL-compatible: low = active, high = shutdown); pulls quiescent current to 1 µA |
| 6, 7 | IN | Main input voltage supply pins; dual routing reduces IR drop and improves transient response |
| 13, 14 | OUT | Regulated 5-V output; dual pins reduce trace resistance and improve current sharing |
| 15 | FB/NC | No-connect for fixed-output version; unused feedback node (not connected internally) |
| 16 | RESET | Open-drain reset output; requires external pullup; asserts low during undervoltage condition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76733QPWPRQ1 | 3.3-V fixed output; identical package, pinout, and feature set except output voltage and RESET threshold scaled to 3.3 V | Designed for 3.3-V digital logic rails (e.g., FPGA I/O, Ethernet PHY), not 5-V MCU cores | Select only when system requires 3.3-V output; not a drop-in replacement for 5-V applications |
| TLV76750QWDRBRQ1 | 5-V output, 1-A rating, but uses NMOS pass element; 250-mV dropout, 25-µA IQ, no integrated RESET, SOT-23-5 package | Lacks RESET function and thermal shutdown; smaller footprint but lower power handling (0.7 W max) | Use where RESET is handled externally and thermal margin is sufficient; not suitable for high-ambient or safety-critical reset functions |
Compared with TPS76733QPWPRQ1 and TLV76750QWDRBRQ1, the TPS76750QPWPRQ1 uniquely combines 5-V output, automotive qualification, integrated 200-ms RESET, and 2.9-W thermal capability in PWP package - making it irreplaceable for ECU and gateway applications requiring deterministic reset and high-temperature reliability.

FAQ
What is the minimum input voltage required for stable operation of the TPS76750QPWPRQ1?
The minimum input voltage for the TPS76750QPWPRQ1 is calculated as VO + VDO(max), which equals 5.0 V + 0.38 V = 5.38 V. Per datasheet Section 6, the recommended minimum input is 6.0 V to ensure regulation across temperature and load extremes. Below 6.0 V, dropout behavior increases and RESET may assert prematurely.
Does the TPS76750QPWPRQ1 require an external pullup resistor on the RESET pin?
Yes, the TPS76750QPWPRQ1 RESET pin is open-drain and requires an external pullup resistor to a valid logic-high voltage (e.g., 5 V or 3.3 V). Typical values range from 10 kΩ to 100 kΩ. Without pullup, RESET remains floating and cannot drive downstream reset logic reliably.
Can the TPS76750QPWPRQ1 be used with ceramic output capacitors?
Yes, the TPS76750QPWPRQ1 is stable with 10-µF ceramic capacitors provided their equivalent series resistance (ESR) is between 50 mΩ and 1.5 Ω. Most commercial 10-µF X5R/X7R MLCCs meet this requirement; verify ESR at 100 kHz in manufacturer datasheets before final selection.
What happens to the output of the TPS76750QPWPRQ1 when the EN pin is driven high?
When EN is driven high (≥1.7 V), the TPS76750QPWPRQ1 enters shutdown mode: the pass transistor turns off, output voltage collapses, and quiescent current drops to 1 µA at 25°C (≤10 µA over −40°C to 125°C). The RESET pin remains high-impedance unless VO falls below threshold.
Is the TPS76750QPWPRQ1 pin-compatible with other devices in the TPS767xx family?
Yes, all TPS767xx devices in the PWP package - including TPS76733QPWPRQ1, TPS76725QPWPRQ1, and TPS76750QPWPRQ1 - share identical pinout, package dimensions, and thermal pad layout. Only output voltage, RESET threshold, and internal resistor divider differ; no PCB redesign is needed when swapping within the family.
