Product details
Overview
TPS76625DRG4 from Texas Instruments is a 250mA, low-dropout linear voltage regulator with fixed 2.5V output, supporting 2.5V–16V input and delivering ±1% output accuracy over load and temperature. It features open-drain power-good (PG), enable (EN) control, thermal shutdown, and stable operation with ≥2.2µF output capacitance - used in HVAC control modules, automotive body electronics, and industrial MCU power rails.
For engineers reviewing the TPS76625DRG4 datasheet, TPS76625DRG4 pinout, TPS76625DRG4 application, or TPS76625DRG4 equivalent, key selection criteria include dropout voltage at 250mA (270mV typ), PSRR of 46dB at 1MHz, internal soft-start (750µs), and compatibility with low-ESR ceramic capacitors in space-constrained SOIC-8 layouts.
Technical Context
The TPS76625DRG4 implements a PMOS pass transistor architecture enabling low dropout and high PSRR. Its feedback loop uses an internal 0.8V reference for fixed-output variants, with PG threshold set at 91–98.5% of VOUT and hysteresis of 0.45% VO.
It operates across –40°C to +125°C junction temperature, supports EN-controlled sleep mode (standby current ≤6.75µA), and maintains regulation under transient loads up to 250mA with <35mV load regulation error and <1.6% total output variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 2.5V ±1% over –40°C to +125°C and full load range (10µA–250mA) |
| Input voltage range | 2.5V to 16V - enables direct use with 12V rails and transformer secondaries |
| Max output current | 250mA continuous - sufficient for powering MCUs, sensors, and gate drivers |
| Dropout voltage | 270mV typical at 250mA - ensures regulation down to VIN = 2.77V |
| PSRR @ 1MHz | 46dB - suppresses switching noise from upstream DC/DC converters |
| Quiescent current | 55µA typical (no load); 1080µA max at 250mA - balances efficiency and transient response |
| Power-good threshold | 91–98.5% of VOUT with 0.45% hysteresis - provides reliable power-on reset signaling |
| Start-up time | 750µs typical - limits inrush current and eases input capacitor sizing |
Pinout & Package
TPS76625DRG4 is housed in an 8-pin SOIC package (D), measuring 4.9mm × 6mm, with exposed pad not present and RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pins 5,6) | Input supply connection | Dual-input pins reduce trace resistance and improve thermal distribution; requires ≥1µF input capacitor placed near both pins |
| OUT (Pins 7,8) | Regulated output | Dual-output pins lower current density and ESR impact; supports ≥2.2µF ceramic output capacitor |
| GND (Pin 3) | Ground reference | Primary return path for load, bias, and feedback currents; must connect to low-impedance ground plane |
| EN (Pin 4) | Enable control input | TTL-compatible; logic-low enables regulator, logic-high disables (standby current ≤6.75µA) |
| PG (Pin 2) | Open-drain power-good | Active-high signal indicating VOUT within regulation; requires external pullup for system reset sequencing |
| FB/NC (Pin 1) | Feedback / No-connect | Not connected internally for fixed-output TPS76625DRG4; leave floating or tie to GND for thermal improvement |
Key Features
| Feature | Design Value |
|---|---|
| Stable with 2.2µF ceramic output cap | Reduces BOM count and board area vs. larger tantalum or electrolytic capacitors |
| 750µs internal soft-start | Minimizes input inrush current, allowing smaller input bulk capacitors and easing hot-swap compliance |
| 46dB PSRR at 1MHz | Attenuates high-frequency switching noise from buck converters without additional LC filtering |
| Open-drain PG with 0.45% hysteresis | Enables clean, glitch-free power-on reset generation for microcontrollers and FPGAs |
| Thermal shutdown with 173°C trip | Protects against sustained overload or poor PCB thermal design while allowing safe transient overloads |
| 1% output accuracy over temp/load | Eliminates need for post-regulation trimming in precision analog or ADC reference supplies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76725 | Higher quiescent current (85µA typ), no PG output, same SOIC-8 package | Lacks power-good signaling; unsuitable where system reset coordination is required | Select when PG functionality is unnecessary and cost sensitivity outweighs noise/efficiency trade-offs |
| MCP1702T-2502E/MB | 250mA, 2.5V fixed, but only 6V max input and 65dB PSRR at 1kHz (not 1MHz) | Lower input voltage rating limits use in 12V systems; inferior high-frequency noise rejection | Prefer for low-voltage embedded designs (<6V input) where ultra-low IQ (2µA) is critical over PSRR |
Compared with TPS76625DRG4, TPS76725 omits PG and trades PSRR for lower cost, while MCP1702T-2502E/MB sacrifices input voltage range and MHz-range ripple rejection for ultra-low standby current - making TPS76625DRG4 optimal for 12V industrial and automotive LDO applications requiring PG, wide VIN, and high-frequency noise immunity.

FAQ
What is the maximum input voltage rating for the TPS76625DRG4?
The TPS76625DRG4 supports an absolute maximum input voltage of 18V, with recommended operating range from 2.5V to 16V. This allows direct integration with 12V automotive and industrial rails while maintaining margin against load-dump transients.
Does the TPS76625DRG4 require an external feedback resistor network?
No - the TPS76625DRG4 is a fixed-output variant with internal resistor divider setting 2.5V. Pin 1 (FB/NC) is not connected; it may be left floating or tied to GND for improved thermal performance, but must not be used for external feedback.
What output capacitor value is required for stable operation of the TPS76625DRG4?
The TPS76625DRG4 is stable with a minimum 2.2µF ceramic output capacitor (X5R/X7R, ≤100mΩ ESR). Larger values (e.g., 4.7µF–22µF) improve transient response and PSRR, but are not required for basic stability.
How does the power-good (PG) pin function on the TPS76625DRG4?
The PG pin is an open-drain output that goes high when VOUT reaches 91–98.5% of nominal 2.5V and remains high until VOUT drops below that threshold minus 0.45% hysteresis. An external pullup resistor (typically 10–100kΩ to VOUT or system rail) is required for proper logic-level signaling.
Can the TPS76625DRG4 be used in automotive applications?
Yes - the TPS76625DRG4 operates across –40°C to +125°C junction temperature, supports 16V input (covering 12V battery + transients), includes thermal shutdown (173°C trip), and is qualified for automotive body electronics per TI's standard reliability testing - though AEC-Q100 qualification status must be verified per specific device lot.
