Product details
Overview
TPS73225DBVTG4 from Texas Instruments is a capacitor-free, NMOS-based low-dropout linear regulator delivering 250mA output current with 40mV typical dropout at full load, 0.5% initial accuracy, and 30μVRMS output noise (10kHz–100kHz). It operates from 1.7V to 5.5V input and provides reverse current protection-ideal for powering noise-sensitive VCOs in portable RF modules.
For engineers reviewing the TPS73225DBVTG4 datasheet, TPS73225DBVTG4 pinout, TPS73225DBVTG4 application, or TPS73225DBVTG4 equivalent, key selection criteria include ultra-low-noise regulation without output capacitance, NMOS topology enabling <1µA shutdown current, and fixed 2.5V output with NR pin for optional noise reduction.
Technical Context
The TPS73225DBVTG4 uses an NMOS pass transistor driven by an internal 4MHz charge pump, eliminating output capacitor stability requirements while maintaining sub-150mV dropout across temperature and load. Its voltage-follower architecture ensures near-constant ground pin current regardless of output current magnitude.
Reverse current protection is achieved via NMOS topology with <10µA reverse leakage (VEN ≤ 0.5V), and noise reduction is enabled through a dedicated NR pin accepting a 0.01µF capacitor to lower output noise to ~12.75µVRMS-critical for VCO supply integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 2.5V - eliminates external feedback resistors and simplifies layout for stable point-of-load regulation. |
| Max Output Current | 250mA - sufficient for powering DSP cores, FPGA I/O banks, or microprocessor peripherals without thermal derating in SOT-23. |
| Dropout Voltage | 40mV typical at 250mA - enables operation with minimal VIN–VOUT headroom (e.g., 2.54V input for 2.5V output), extending battery life in 2-cell Li-ion systems. |
| Output Noise | 30μVRMS (10kHz–100kHz) - meets stringent phase noise requirements for RF synthesizers when used with NR capacitor. |
| Shutdown Current | <1µA - preserves battery energy during system sleep modes without requiring external discharge paths. |
| Accuracy | ±1% over line/load/temperature - ensures consistent voltage margining for logic interfaces and analog references without calibration. |
| Input Voltage Range | 1.7V to 5.5V - supports direct regulation from single Li-ion, USB, or post-switching-supply rails without intermediate stages. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9mm × 2.8mm footprint with exposed pad not present; suitable for high-density portable PCBs and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (Pin 1) | Input supply connection | Accepts 1.7V–5.5V; must be decoupled locally to suppress switching noise from upstream converters. |
| GND (Pin 2) | Power ground reference | Common return for IN, OUT, EN, and NR; requires low-inductance PCB trace to minimize ground bounce. |
| EN (Pin 3) | Enable control input | Active-high TTL/CMOS-compatible; drives regulator ON above 1.7V, OFF below 0.5V with <1µA shutdown current. |
| NR (Pin 4) | Noise reduction node | Connects external 0.01µF capacitor to GND to reduce output noise by ~2.4×; not present on adjustable versions. |
| OUT (Pin 5) | Regulated output | Delivers stable 2.5V ±1%; no minimum ESR or capacitance required for stability-enables capacitor-free designs. |
Key Features
| Feature | Design Value |
|---|---|
| Capacitor-free operation | Stable with zero output capacitance-removes BOM cost, board space, and aging/reliability concerns of bulk capacitors. |
| NMOS reverse current blocking | <10µA reverse leakage at VEN ≤ 0.5V-prevents backfeed into depleted batteries or failed upstream supplies. |
| Integrated noise reduction (NR) pin | Enables 12.75µVRMS output noise with 0.01µF CNR-meets VCO phase noise specs without LDO post-filtering. |
| Ultra-low ground pin current | 400–950µA across 0–250mA load-minimizes power loss and improves efficiency at light loads. |
| Thermal & foldback protection | 160°C shutdown with hysteresis and current limit decreasing below 0.5V VOUT-safeguards against short-circuit faults without external circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS73225DBVR | Same silicon, tape-and-reel packaging (3000-unit reel vs. 250-unit cut tape); identical electrical specs and pinout. | No functional difference-used interchangeably in production; DBVTG4 is cut-tape variant for prototyping and low-volume builds. | Select DBVTG4 for evaluation and small-batch assembly; DBVR for high-volume automated placement. |
| MCP1702T-2502E/MB | 250mA CMOS LDO with 600mV dropout at full load, 65µVRMS noise, no NR pin, and 2% accuracy-higher dropout and noise than TPS73225DBVTG4. | Suitable only where 2.5V tolerance >±2% and noise <65µVRMS is acceptable; cannot replace in VCO or precision analog paths. | Choose only if cost sensitivity outweighs performance needs and layout allows higher VIN headroom. |
Compared with TPS73225DBVTG4, TPS73225DBVR offers identical performance in volume packaging, while MCP1702T-2502E/MB trades off 15× higher dropout and 2× higher noise for lower unit cost-making it viable only in non-critical digital I/O rails.

FAQ
What is the maximum input voltage rating for the TPS73225DBVTG4?
The TPS73225DBVTG4 has an absolute maximum input voltage of 6V, but its recommended operating range is 1.7V to 5.5V. Exceeding 5.5V may trigger internal protection or cause permanent damage. For reliable operation in 5V rail applications, ensure transient spikes remain below 6V using appropriate clamping or filtering-TPS73225DBVTG4 itself does not include overvoltage protection beyond its absolute ratings.
Does the TPS73225DBVTG4 require an output capacitor for stability?
No, the TPS73225DBVTG4 is explicitly designed for capacitor-free operation due to its NMOS pass transistor and internal compensation. Stability is maintained with zero output capacitance, though adding up to 10µF improves transient response. This eliminates ESR dependency and reliability risks associated with electrolytic or tantalum capacitors-TPS73225DBVTG4 remains stable across ceramic, polymer, or no output cap.
How does the NR pin on the TPS73225DBVTG4 reduce output noise?
The NR pin on the TPS73225DBVTG4 connects to an internal 27kΩ resistor in series with the bandgap reference, forming a low-pass filter when a capacitor (e.g., 0.01µF) is placed from NR to GND. This reduces broadband reference noise contribution, lowering total output noise from 30μVRMS to ~12.75μVRMS (10kHz–100kHz). The TPS73225DBVTG4's NR functionality is exclusive to fixed-output variants and is not available on adjustable versions.
What is the shutdown current specification for the TPS73225DBVTG4?
The TPS73225DBVTG4 draws less than 1µA of ground pin current in shutdown mode (VEN ≤ 0.5V), with typical values around 0.02µA at room temperature. This ultra-low quiescent current extends battery runtime in always-on sensor nodes and portable devices-TPS73225DBVTG4 achieves this without external discharge circuitry, as the NMOS gate fully discharges when disabled.
Can the TPS73225DBVTG4 be used in automotive applications?
The TPS73225DBVTG4 is rated for –40°C to +125°C junction temperature and features thermal shutdown and foldback current limiting-meeting baseline environmental robustness for under-hood or infotainment use. However, it is not AEC-Q100 qualified, lacks automotive-specific qualification testing (e.g., HTOL, ESD stress levels), and TI positions it for industrial and portable consumer applications-not automotive safety-critical systems. Use TPS73225DBVTG4 only in non-safety automotive subsystems with full system-level validation.
