Product details
Overview
TPS73130DBVRG4 from Texas Instruments is a capacitor-free, NMOS-based 150mA low-dropout linear regulator with reverse current protection and fixed 3.0V output. It operates from 1.7V to 5.5V input, delivers ultra-low 30mV typical dropout at full load, and achieves 0.5% initial accuracy and 30μVRMS output noise (10kHz–100kHz) - ideal for powering noise-sensitive VCOs in wireless infrastructure and medical equipment.
For engineers reviewing the TPS73130DBVRG4 datasheet, TPS73130DBVRG4 pinout, TPS73130DBVRG4 application, or TPS73130DBVRG4 equivalent, this page provides verified specifications, SOT-23-5 pin functions, real-world use cases in building automation and test equipment, and two validated alternative LDOs with documented functional and parametric differences.
Technical Context
The TPS73130DBVRG4 uses an NMOS pass transistor with integrated 4MHz charge pump to drive the gate above VOUT, enabling stable regulation without output capacitance and delivering <100mV dropout at 150mA. Its voltage-follower topology ensures stability across capacitor types and values - including zero-output-capacitor operation.
It integrates reverse-current blocking via NMOS gate control, thermal shutdown at 160°C, foldback current limiting (150–500mA), and a dedicated NR pin for noise reduction (0.01µF to ground cuts output noise to ~8.5×VOUT µVRMS). Ground pin current remains near-constant (400–750µA) over load and temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 3.0V ±1% over line/load/temperature - enables direct replacement of 3.3V or 3.0V logic rails without external resistors. |
| Dropout Voltage | 30mV typical at 150mA - supports regulation down to VIN = 3.03V, critical for battery-powered systems near end-of-life. |
| Output Noise | 30μVRMS (10kHz–100kHz) with no CNR; reduced to ~25.5μVRMS with 0.01µF NR capacitor - meets VCO phase-noise requirements. |
| Shutdown Current | <1μA max - preserves battery life in portable medical and smart grid endpoints during sleep mode. |
| Input Voltage Range | 1.7V to 5.5V - compatible with single-cell Li-ion (2.7–4.2V), USB (4.75–5.25V), and 3.3V/5V rail inputs. |
| Accuracy | 0.5% initial tolerance - eliminates need for post-production calibration in precision analog signal chains. |
| Thermal Protection | 160°C shutdown / 140°C restart - prevents thermal runaway in enclosed industrial enclosures or high-density PCBs. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9mm × 2.8mm footprint, surface-mount, thermally enhanced with exposed pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input supply connection | Accepts 1.7–5.5V DC; internal ESD protection rated to ±2000V HBM; requires no input capacitor but benefits from local 100nF ceramic for PSRR. |
| GND (Pin 2) | Power ground reference | Low-impedance return path; ground pin current varies only 150µA from 10mA to 150mA load - simplifies power integrity analysis. |
| EN (Pin 3) | Enable control input | Active-high TTL/CMOS-compatible; <0.5V disables regulator (IQ <1μA); >1.7V enables; internally pulled down when floating. |
| NR (Pin 4) | Noise reduction node | Fixed-output version only; connects external 0.01µF capacitor to GND to reduce output noise by ~3× - essential for RF subsystems. |
| OUT (Pin 5) | Regulated output | 3.0V source capable of 150mA; zero-output-capacitor stable; no ESR constraints - supports ceramic, tantalum, or polymer caps interchangeably. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitor-free stability | Operates reliably with 0µF output capacitance - eliminates BOM cost, board space, and aging-related drift in timing-critical applications. |
| Reverse current blocking | IREV ≤10µA (VOUT=3.0V, VIN=0V) - prevents backfeed into shared input rails in multi-rail systems like point-of-sale terminals. |
| Ultra-low noise architecture | 30μVRMS (10kHz–100kHz) + NR pin option - meets stringent spectral purity requirements for VCOs in wireless infrastructure base stations. |
| Advanced BiCMOS process | Enables 0.5% initial accuracy and <100mV dropout at 150mA - achieves precision performance without external trimming components. |
| Integrated foldback current limit | 150mA nominal limit, drops to 0mA below –0.2V VOUT - protects against short-circuit damage while avoiding latch-up in fault recovery. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, capacitor-free LDO applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS73230DBVR | Same 3.0V fixed output, but uses PMOS pass device; requires minimum 1µF output capacitor; 120mV dropout at 150mA. | Lacks reverse current blocking and NR pin; higher dropout limits use in low-VIN battery apps. | Select when lower quiescent current (400nA) is prioritized over reverse blocking and noise performance. |
| MCP1703T-3002E/MB | 3.0V fixed output, 600mA rating, 350mV dropout at full load; requires 1µF ceramic output cap; no NR pin or reverse blocking. | Higher current capability but significantly higher noise (110μVRMS) and less precision (2% total accuracy). | Choose for cost-sensitive, non-noise-critical 3.0V rails where higher dropout and accuracy tolerance are acceptable. |
Compared with TPS73130DBVRG4, TPS73230DBVR trades reverse-current protection and ultra-low noise for lower IQ, while MCP1703T-3002E/MB offers higher current at the expense of noise, accuracy, and capacitor-free operation - making TPS73130DBVRG4 optimal for VCO bias and precision analog supply where those attributes are mandatory.

FAQ
What is the maximum input voltage for the TPS73130DBVRG4?
The TPS73130DBVRG4 supports a maximum input voltage of 5.5V under recommended operating conditions. Exceeding this value risks permanent damage, as the absolute maximum rating is 6.0V - transient spikes above 5.5V must be suppressed using TVS diodes or RC filters in the TPS73130DBVRG4 design.
Does the TPS73130DBVRG4 require an output capacitor to operate stably?
No, the TPS73130DBVRG4 is explicitly designed for capacitor-free operation and remains stable with 0µF output capacitance. This is enabled by its NMOS pass transistor topology and internal compensation - though adding a 1µF ceramic capacitor improves load transient response without affecting stability.
How does the NR pin on the TPS73130DBVRG4 reduce output noise?
The NR pin on the TPS73130DBVRG4 connects to an internal 27kΩ resistor in series with the bandgap reference. Adding a 0.01µF capacitor from NR to GND forms a low-pass filter that reduces output noise to ~8.5×VOUT µVRMS (e.g., ~25.5µVRMS at 3.0V) - a ~3× improvement over the base 30µVRMS specification.
What is the reverse leakage current specification for the TPS73130DBVRG4?
The TPS73130DBVRG4 specifies reverse leakage current (IREV) of ≤10µA maximum when VOUT = 3.0V and VIN = 0V. This low reverse current is achieved via NMOS gate control and enables safe use in systems with shared input buses or backup battery paths where backfeed must be prevented.
Can the TPS73130DBVRG4 be used in automotive applications?
The TPS73130DBVRG4 is not AEC-Q100 qualified and has an operating junction temperature range of –40°C to 125°C - suitable for under-hood industrial applications but not certified for automotive safety-critical systems. For automotive use, TI recommends the pin-compatible AEC-Q100 qualified TPS7B67xx family instead of the TPS73130DBVRG4.
