Product details
Overview
TPS76350DBVRG4 from Texas Instruments is a fixed-output 5.0V, 150mA low-dropout linear voltage regulator in a 5-pin SOT-23 (DBV) package. It operates from 2.7V to 10V input, delivers ±1.0% output accuracy (typical, new chip), features 175mV typical dropout at 150mA, and supports –40°C to 125°C junction temperature - enabling reliable power for battery-powered smoke detectors and electricity meters.
For engineers reviewing the TPS76350DBVRG4 datasheet, TPS76350DBVRG4 pinout, TPS76350DBVRG4 application, or TPS76350DBVRG4 equivalent, this page provides verified electrical specs, thermal performance data, enable-controlled sleep mode behavior, and real-world transient response characteristics critical for low-power, space-constrained industrial sensing designs.
Technical Context
The TPS76350DBVRG4 implements a PMOS pass transistor architecture with internal soft-start and active overshoot pulldown protection. Its enable pin (EN) accepts logic-level control (0.15V low threshold, 0.85V high threshold for new chip), allowing precise system-level power sequencing and shutdown to 1μA standby current.
It uses a fixed-voltage feedback network (no external resistors), integrates thermal shutdown and overcurrent limiting, and is optimized for stability with ≥1μF ceramic output capacitance (derated 50%). The device's 178.6°C/W junction-to-ambient thermal resistance reflects its SOT-23-5 (DBV) package's thermal performance under standard PCB layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 5.0V ±1.0% (typical, new chip) across –40°C to 125°C, 1mA–150mA load - ensures stable MCU core supply under wide temperature and load variation. |
| Max Output Current | 150mA continuous - sufficient for powering microcontrollers, sensors, and RF transceivers in portable metering and security devices. |
| Dropout Voltage | 175mV (typical) at 150mA - enables operation from single Li-ion (3.0V min) or two alkaline cells (3.2V min) while maintaining regulation. |
| Quiescent Current | 65μA (typical) at zero load; 765μA (typical) at 150mA - minimizes battery drain during idle and active states in always-on sensing nodes. |
| Enable Threshold | EN high = ≥0.85V, low = ≤0.15V - compatible with 1.8V/3.3V GPIOs without level-shifting; tie-to-VIN for always-on operation. |
| Thermal Shutdown | Active protection triggered above 150°C junction temperature - prevents damage during overload or poor heatsinking in sealed enclosures. |
| PSRR | 58dB at 1kHz - suppresses ripple from switching pre-regulators or noisy battery sources, improving ADC reference stability. |
Pinout & Package
TPS76350DBVRG4 is housed in a 5-pin SOT-23 (DBV) package measuring 2.9mm × 2.8mm, with RθJA = 178.6°C/W. The pinout is standardized across the TPS763 family and validated per TI SLVS181K Rev. December 2025.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: IN | Input supply connection | Accepts 2.7V–10V; requires ≥0.47μF ceramic input capacitor close to pin for stability and transient response. |
| 2: GND | Power ground reference | Low-impedance return path for input/output currents; must be connected directly to PCB ground plane. |
| 3: EN | Logic-enable control input | Drives high (>0.85V) to activate regulator; drives low (<0.15V) to enter 1μA standby mode - enables system-level power gating. |
| 4: NC | No connection | Internally unconnected; must remain floating - not used in fixed-output variants like TPS76350DBVRG4. |
| 5: OUT | Regulated output terminal | Delivers 5.0V; requires ≥2.2μF ceramic output capacitor (50% derating) for loop stability and load transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Active overshoot pulldown | Clamps output voltage during fast input rise or load release - prevents damaging overvoltage on downstream 5V-tolerant ICs. |
| Internal soft-start | Controls inrush current at startup - reduces required input capacitance and avoids brownout on weak supplies like coin cells. |
| Logic-enabled sleep mode | Reduces quiescent current to ≤1μA at TJ = 25°C - extends battery life in intermittently active sensor nodes by >100× vs active mode. |
| Thermal & overcurrent protection | Auto-recovering shutdown at >150°C junction or >1.05A short-circuit - maintains reliability without external circuitry in harsh environments. |
| Low-noise operation | 165µVRMS output noise (300Hz–50kHz, 3.3V out, 4.7µF COUT) - suitable for analog signal chains and precision references. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS76350DBVT | Same silicon, tape-and-reel vs cut-tape packaging; identical electrical specs and thermal performance. | No functional difference; selected for automated SMT assembly requiring full reel delivery. | Choose TPS76350DBVT when volume production requires standard 3,000-unit reels and no manual handling. |
| MCP1700T-5002E/TT | 100mA max output, 6μA quiescent current (vs 65μA), 2% output tolerance, SOT-23-3 package (no EN pin). | Lacks enable control and thermal shutdown; suited for simpler, lower-current always-on loads without sequencing needs. | Choose MCP1700T-5002E/TT only for cost-sensitive, non-safety-critical applications where 100mA and no enable are acceptable. |
Compared with TPS76350DBVRG4, TPS76350DBVT offers identical performance in reel format for high-volume manufacturing, while MCP1700T-5002E/TT trades enable functionality, thermal protection, and 50mA headroom for ultra-low quiescent current - making it viable only in simplified, lower-power use cases.

FAQ
What is the maximum input voltage rating for the TPS76350DBVRG4?
The TPS76350DBVRG4 has an absolute maximum input voltage of 18V for the new-chip revision, but its recommended operating range is 2.7V to 10V. Exceeding 10V continuously may degrade long-term reliability or trigger overvoltage protection mechanisms not explicitly documented for this variant. Always refer to the latest TI SLVS181K datasheet for safe operating area limits.
Does the TPS76350DBVRG4 require an external feedback resistor network?
No, the TPS76350DBVRG4 is a fixed-output 5.0V regulator and does not require external feedback resistors. Pin 4 (FB/NC) is internally connected to the voltage divider and must be left unconnected (NC) - unlike adjustable TPS763 variants which use this pin for external resistor programming.
What is the minimum output capacitance required for stable operation of the TPS76350DBVRG4?
The TPS76350DBVRG4 requires a minimum output capacitance of 1μF (ceramic, 50% derated), with 2.2μF recommended for optimal transient response and PSRR. The device is stable with low-ESR ceramic capacitors and does not require tantalum or electrolytic types - simplifying BOM and improving reliability in temperature-cycling environments.
How does the enable pin (EN) behave during power-up for the TPS76350DBVRG4?
The TPS76350DBVRG4 EN pin has a 0.15V low threshold and 0.85V high threshold (new-chip spec). When VIN rises, EN must exceed 0.85V to activate regulation; if EN is tied to VIN, the device powers up synchronously with input. Internal pull-down ensures default disable if EN is left floating - preventing unintended startup.
Can the TPS76350DBVRG4 be used in automotive applications?
The TPS76350DBVRG4 is specified for –40°C to 125°C junction temperature and includes thermal shutdown, but it is not AEC-Q100 qualified. It may be used in under-hood or cabin applications only after full system-level qualification, including extended temperature cycling, ESD, and EMC testing - TI does not guarantee automotive-grade reliability for this part.
