Product details
Overview
TPS77025DBVRG4 from Texas Instruments is a fixed-output, 2.5V ultra-low-power low-dropout linear regulator in SOT-23-5 package, supporting 2.5V–16V input, delivering up to 100mA with ±1.2% output accuracy over load and temperature, 215mV typical dropout at 100mA, and integrated thermal shutdown and overcurrent protection - used for biasing microcontrollers and sensors in HVAC control modules.
For engineers reviewing the TPS77025DBVRG4 datasheet, TPS77025DBVRG4 pinout, TPS77025DBVRG4 application, or TPS77025DBVRG4 equivalent, key selection criteria include its 1.2% output accuracy, 46dB PSRR at 1MHz, 750µs internal soft-start, 2.2µF minimum output capacitance requirement, and −55°C to +150°C junction temperature range for industrial embedded power rails.
Technical Context
The TPS77025DBVRG4 implements a PMOS pass transistor architecture enabling low quiescent current (50–95µA) and stable operation with ceramic output capacitors as low as 2.2µF. Its internal 1.2V reference and error amplifier regulate output via feedback from the FB/NC pin - though this pin is unconnected (NC) in the fixed 2.5V variant.
It integrates undervoltage lockout (UVLO) with 2.2V rising threshold and 1.9V falling threshold, plus enable logic with 0.415V low-level and 1.6V high-level thresholds. Thermal shutdown activates at 173°C and resets at 157°C, ensuring robust fault recovery in thermally constrained environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output voltage | Fixed 2.5V ±1.2% over full load (0–100mA) and temperature (−40°C to +125°C) |
| Input voltage range | 2.5V to 16V - supports direct regulation from 12V automotive or industrial rails without pre-regulation |
| Dropout voltage | 215mV (typ) at 100mA - enables stable 2.5V output even when input drops to 2.715V |
| PSRR | 46dB at 1MHz - suppresses switching noise from upstream DC/DC converters, reducing need for post-filtering |
| Quiescent current | 50–95µA (adjustable/fixed variants), 620µA at 100mA load - optimized for battery-backed or always-on systems |
| Output capacitor | ≥2.2µF ceramic (ESR ≤3Ω) - enables compact, low-ESR capacitor selection and reduces board area |
| Enable threshold | High-level: ≥1.6V; Low-level: ≤0.415V - compatible with 1.8V/3.3V GPIO without level-shifting |
Pinout & Package
TPS77025DBVRG4 is housed in a 5-pin SOT-23 (DBV) package measuring 2.9mm × 2.8mm with RθJA = 178.6°C/W, suitable for space-constrained PCB layouts and thermally demanding industrial applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - IN | Input supply connection | Accepts 2.5V–16V; requires 1µF input capacitor placed adjacent to IN/GND pins for stability |
| 2 - GND | Power ground reference | Common return path for input, output, and internal circuitry; must be low-impedance |
| 3 - EN | Active-high enable control | Pull ≥1.6V to enable regulator; ≤0.415V disables output and reduces quiescent current to 0.9–2.75µA |
| 4 - FB/NC | Feedback / No-connect | No connection (NC) in fixed-output TPS77025DBVRG4; must remain unconnected per datasheet |
| 5 - OUT | Regulated 2.5V output | Delivers up to 100mA; requires ≥2.2µF ceramic capacitor with ESR ≤3Ω placed adjacent to OUT/GND |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low quiescent current | 50–95µA (standby), enabling >10-year battery life in low-duty-cycle sensor nodes |
| Integrated soft-start | 750µs typical - limits inrush current, allowing smaller input capacitance and reducing stress on upstream supplies |
| High-accuracy output | ±1.2% over load/temperature - eliminates need for external trimming in precision analog or ADC reference rails |
| Wide-input UVLO | 2.2V turn-on / 1.9V turn-off with 0.13V hysteresis - prevents erratic startup during brownout conditions |
| Robust fault protection | Thermal shutdown (173°C), overcurrent limit (370–450mA), and internal pulldown - ensures safe failure mode under overload |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76925DBVR | Legacy variant: 3% output accuracy, 71mV dropout at 100mA, 4.7µF min COUT, 13.5V max input | Lower accuracy and higher dropout limit use in cost-sensitive, non-automotive designs with stable 5V–10V inputs | Choose for legacy designs where 3% tolerance is acceptable and input voltage stays below 10V |
| MCP1700T-2502E/TT | Microchip part: 2% accuracy, 178mV dropout at 250mA, 1.6V–6.0V input, no enable pin, SOT-23-3 package | Lacks enable and UVLO; limited to ≤6V input - unsuitable for 12V automotive or industrial rails | Select only for low-voltage, enable-free applications where 6V max input and 2% accuracy meet requirements |
Compared with TPS76925DBVR and MCP1700T-2502E/TT, the TPS77025DBVRG4 provides superior accuracy (±1.2%), wider input range (up to 16V), integrated enable/UVLO, and lower output capacitance requirement - making it optimal for next-generation industrial and automotive LDO applications requiring reliability and design margin.

FAQ
What is the maximum input voltage rating for the TPS77025DBVRG4?
The TPS77025DBVRG4 has an absolute maximum input voltage of 18V, with recommended operating range from 2.5V to 16V. Exceeding 18V risks permanent damage; operation above 16V is outside specified performance limits and not guaranteed across temperature or load conditions.
Does the TPS77025DBVRG4 require an external feedback resistor network?
No - the TPS77025DBVRG4 is a fixed 2.5V output variant, and Pin 4 (FB/NC) is designated as "No Connection." This pin must remain unconnected; adding external resistors will disrupt regulation and may cause malfunction.
What is the minimum output capacitance required for stable operation of the TPS77025DBVRG4?
The TPS77025DBVRG4 requires a minimum 2.2µF ceramic output capacitor with ESR ≤3Ω. Using less capacitance or higher ESR risks instability, oscillation, or poor transient response - especially under dynamic load changes.
How does the enable pin (EN) function on the TPS77025DBVRG4?
The EN pin is active-high: driving it ≥1.6V enables regulation; ≤0.415V disables the output and reduces quiescent current to 0.9–2.75µA. The pin has no internal pull-up/down, so external logic or resistor biasing is required for defined state control.
Is the TPS77025DBVRG4 suitable for automotive applications?
Yes - the TPS77025DBVRG4 supports −40°C to +125°C operating junction temperature, includes UVLO (2.2V turn-on), thermal shutdown (173°C), and handles 16V input - meeting core requirements for non-safety-critical automotive body electronics such as door modules and climate controls.
