TPS70351PWPR

TPS70351PWPR is TI’s fixed-output low-dropout regulator (LDO) in the TPS7035x family. It is designed to provide a stable supply to microcontrollers, sensors, and other loads from a higher input voltage with ultra-low quiescent current, making it suitable for battery-powered designs. Key features typically include a fixed output voltage (exact value in the datasheet), enable/shutdown control, low dropout, protection options (overcurrent and thermal shutdown), and very low quiescent current for long battery life. The PWPR suffix denotes a specific small-package variant used on boards. For exact output voltage, input range, current capability, pinout, and package details, consult the TPS70351 datasheet and TI product page.

TPS70351PWPR is TI's fixed‑output LDO in the TPS7035x/703x family (≈150 mA). There isn’t a single published “exact equivalent.” Use TI’s Cross Reference tool to map to TI parts with the same voltage/current and package. External 150 mA LDO equivalents (voltage dependent) include MIC5205, MCP1700-3302E, LP2985-3.3, and ADP1700-3.3.

TPS70351PWPR is TI’s ultra-low-quiescent LDO regulator. Key features:
- Fixed-output LDO with enable pin for power-saving control
- Very low quiescent current (microamp range) for long battery life
- Low dropout voltage for operation with low headroom
- Fixed output options (e.g., common voltages such as 1.8 V, 2.5 V, 3.3 V) with high accuracy
- Input range suitable for low-voltage supplies
- Overcurrent/short-circuit protection and thermal shutdown for protection
- Fast transient response and good power-supply rejection (PSRR
- Tiny PWPR package (WSON-style), suitable for space-constrained applications
- Wide operating temperature range for various environments
Note: exact output voltage option and electrical specs come from the datasheet; check the specific variant for precise values.

Function: Low-dropout regulator (LDO) that provides a fixed output voltage with an enable control.

- Manufacturer: Texas Instruments (TI).
- What kind of company: an American multinational semiconductor company that designs and manufactures analog and mixed-signal ICs, embedded processing, sensors, and related electronics.

TPS70351PWPR is an ultra-low-quiescent-current LDO regulator in a compact package. It suits battery-powered and space-constrained designs needing a clean, regulated rail. Typical application areas:
- Microcontroller, DSP, and peripheral power rails in portable devices
- Sensors, actuators, and RF/wireless modules in IoT nodes
- Wearables and lightweight medical devices
- USB-powered gadgets and general consumer electronics
- Automotive and industrial sensing where a stable low-noise supply is required
Overall, great for any low-power, small-footprint system requiring a reliable LDO output.

The TPS70351PWPR uses an X2SON-6 package (6-pin, 2×3 mm) in tape-and-reel.
