Product details
Overview
TPS70615DRVR from Texas Instruments is a fixed-output 1.5-V, 150-mA ultralow-quiescent-current LDO voltage regulator in a 6-pin WSON package. It delivers 2% output accuracy over –40°C to +125°C, features 1-µA typical quiescent current, reverse current protection, and 245-mV dropout at 50 mA - enabling long battery life in always-on portable systems such as wearables and medical sensors.
For engineers reviewing the TPS70615DRVR datasheet, TPS70615DRVR pinout, TPS70615DRVR application, or TPS70615DRVR equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, application-specific implementation insights, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The TPS70615DRVR uses a PMOS pass transistor architecture to achieve low dropout and inherent reverse current blocking without external components. Its precision band-gap reference and error amplifier maintain ±2% DC output accuracy across temperature and load, while the enable (EN) pin supports active-high logic control with 0.9 V minimum threshold and 150 nA shutdown current.
Thermal shutdown triggers at ~158°C and resets at ~140°C; internal current limiting activates at ≥200 mA to protect against overload. The device operates stably with 2.2-µF ceramic output capacitance and exhibits 190 µVRMS output noise and 80 dB PSRR at 10 Hz - critical for RF-sensitive and low-noise analog subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | Fixed 1.5 V ±2% over –40°C to +125°C - ensures stable biasing for low-voltage MCUs and sensors without external feedback. |
| Quiescent Current | 1 µA typical - extends battery runtime in multi-year IoT endpoints and always-on monitoring devices. |
| Dropout Voltage | 245 mV at 50 mA - enables regulation from 1.745 V input, supporting single-cell LiFePO₄ or dual-cell alkaline operation. |
| Shutdown Current | 150 nA at VEN ≤ 0.4 V - reduces system standby power to near-zero when disabled. |
| Reverse Current Protection | 10 nA max reverse leakage - prevents battery drain when output is back-driven, eliminating need for external blocking diode. |
| PSRR @ 10 Hz | 80 dB - suppresses low-frequency supply ripple from switching converters feeding the LDO input. |
| Output Noise | 190 µVRMS (10 Hz–100 kHz) - suitable for powering ADC references and RF synthesizers without added filtering. |
Pinout & Package
TPS70615DRVR is housed in a thermally enhanced 2.0 mm × 2.0 mm WSON-6 package with an exposed thermal pad electrically tied to GND. The pad must be soldered to a PCB ground plane to achieve RθJA = 73.1°C/W and ensure safe operation at full 150-mA load.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Regulated output | Connect ≥2.2-µF ceramic capacitor to GND; output remains stable only within 2.0–47 µF range and 0–0.2 Ω ESR. |
| 2, 5 (NC) | No internal connection | Not bonded; must remain unconnected - floating or tied to GND has no effect on operation. |
| 3 (GND) | Power ground | Primary return path; connects internally to thermal pad - requires low-impedance PCB ground plane for thermal management. |
| 4 (EN) | Enable control | Active-high logic: ≥0.9 V enables regulation; ≤0.4 V disables with 150-nA shutdown current; can float to default-enable. |
| 6 (IN) | Unregulated input | Accepts 2.7–6.5 V; requires ≥1-µF ceramic bypass capacitor close to pin to suppress high-frequency noise and improve PSRR. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow IQ | 1 µA quiescent current enables >10-year battery life in coin-cell-powered devices drawing <1 µA average system current. |
| Reverse current blocking | 10 nA max reverse leakage eliminates need for external Schottky diode in multi-rail or backup-power systems. |
| Thermal & current protection | Auto-cycling thermal shutdown (158°C trip / 140°C reset) and ≥200 mA current limit prevent damage during sustained overload. |
| Low-noise regulation | 190 µVRMS integrated noise and 80 dB PSRR at 10 Hz support precision analog front-ends and RF ICs. |
| WSON-6 thermal performance | 73.1°C/W junction-to-ambient rating allows 150 mA continuous output at +85°C ambient with minimal copper area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar LDO voltage regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS70615DBVR | SOT-23-5 package (2.9 mm × 1.6 mm); higher RθJA = 212.1°C/W; same electrical specs and pinout mapping (EN/IN/GND/OUT). | Less thermal margin at 150 mA in compact layouts; preferred where board space > thermal performance. | Select TPS70615DBVR only if WSON-6 assembly capability is unavailable and peak load is ≤50 mA. |
| MCP1700T-1502E/TT | 1.5-V fixed output; 1.6-µA IQ; 6-V max VIN; no reverse current protection; SOT-23-3 (no EN pin). | Requires external enable circuitry; lacks reverse blocking - unsuitable for systems with shared or back-driven rails. | Choose MCP1700T-1502E/TT only for cost-sensitive, non-backpowering applications where EN control and reverse protection are unnecessary. |
Compared with TPS70615DBVR, the TPS70615DRVR offers superior thermal performance and smaller footprint; compared with MCP1700T-1502E/TT, it adds critical reverse current blocking and integrated enable functionality - making it the only option for battery-backed or multi-supply systems requiring true isolation.

FAQ
What is the maximum input voltage for the TPS70615DRVR?
The TPS70615DRVR supports a maximum input voltage of 6.5 V under recommended operating conditions. Absolute maximum rating is 7 V, but operation above 6.5 V risks permanent damage and violates TI's specified safe operating area. For reliable long-term use, keep VIN ≤6.5 V across all temperatures and load conditions.
Does the TPS70615DRVR require an input capacitor?
While not required for stability, the TPS70615DRVR benefits from a 1-µF ceramic capacitor placed between IN and GND. This improves high-frequency PSRR, suppresses input ripple, and enhances transient response - especially when fed from noisy switchers or long PCB traces. TI recommends X7R/X5R dielectrics with low ESR.
Can the TPS70615DRVR be used without connecting the EN pin?
Yes - the EN pin of the TPS70615DRVR can be left floating to default-enable the device. Internally, it pulls up to enable operation. However, for deterministic startup or noise immunity in high-EMI environments, TI recommends tying EN directly to IN or using a pull-up resistor to VIN.
What is the minimum output capacitance required for stability with the TPS70615DRVR?
The TPS70615DRVR requires a minimum effective output capacitance of 2.2 µF for stable operation at 1.5 V output. This value accounts for DC bias, temperature, and tolerance derating - so a 2.2-µF X7R ceramic capacitor rated at ≥6.3 V is the standard recommendation per TI's datasheet Figure 30 and Section 8.2.2.
How does reverse current protection work in the TPS70615DRVR?
The TPS70615DRVR integrates active reverse current protection that blocks current flow from OUT to IN whenever VOUT > VIN, limiting leakage to 10 nA typical. This function is always active - independent of EN state - and eliminates external diodes in battery backup or multi-rail systems where output voltage may exceed input.
