概述

Description

TPS70351PWPR is a fixed-output, low-dropout (LDO) regulator from TI’s TPS7030x family, designed for ultra-low quiescent current in compact, battery-powered designs. The PWPR suffix indicates TI’s small, surface-mount package optimized for space-constrained boards.
Key features (typical):
- Fixed output voltage (available in several options; check datasheet for the exact value)
- Enable input (to disable/enable for power-saving operation)
- Very low quiescent current and low dropout
- Overcurrent/short-circuit protection and thermal shutdown
- Small footprint suitable for wearables, IoT sensors, microcontroller power rails, and other portable applications
Typical usage:
- Connect IN to the supply, GND to ground, and OUT to the load
- Drive EN high to enable, low to disable
For precise specifications (input voltage range, exact fixed output voltage, dropout, current limit, and package dimensions), refer to the TI TPS70351PWPR datasheet.

Features

TPS70351PWPR is a fixed-output, low-dropout regulator in the PWPR package. Key features:
- Ultra-low quiescent current
- Low dropout voltage
- Output current up to ~150 mA
- Wide input range (typical 1.8–5.5 V)
- Enable (EN) pin to turn regulator on/off
- Short-circuit and thermal shutdown protection
- Stable with small ceramic output capacitors
- Small, compact 8-pin PWPR package suitable for portable designs
Note: Exact output voltage options, current capability, and temperature range are device-variant specific—consult the datasheet for the precise TPS70351PWPR specifications.

Package

TPS70351PWPR uses an 8-pin VQFN package (3×3 mm) with an exposed pad (EP).

Pinout

- Pin count: 5 pins
- Function: Fixed-output low-dropout regulator (LDO) with an enable/shutdown input, in a PWPR (SOT-23-5) package.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: TI is a global American multinational semiconductor company that designs and manufactures analog and mixed-signal integrated circuits, embedded processing devices, and power-management solutions.

Application

TPS70351PWPR is a low-dropout regulator intended for portable, battery-powered electronics. It is used to provide a stable fixed output rail for microcontrollers, sensors, RF/analog front-ends, and other ICs in IoT devices, wearables, handheld instruments, medical sensors, and consumer electronics. Its compact package and low quiescent current make it ideal for space-limited, power-sensitive embedded designs requiring a reliable supply rail.

Equivalent

TPS70351PWPR is a TI low-dropout regulator. For exact substitutes, use TI’s Cross Reference tool. TI equivalents commonly used include TLV70033, TPS78333, and TPS7A33. Non‑TI 3.3 V LDO options include LM1117‑3.3, AMS1117‑3.3, and LD1117‑3.3. Always verify output voltage, max current, dropout, input range, and package to ensure compatibility.
