概述

Description

TPS70158PWP is a Texas Instruments low-dropout regulator (LDO) from the TPS701x family. It provides a clean, stable voltage for microcontrollers, sensors, and other analog/digital blocks in compact, space‑constrained designs. Key features typically include very low quiescent current, an enable/shutdown control, overcurrent/short-circuit protection and thermal shutdown, and stability with ceramic capacitors. It comes in a small 8‑pin PWP package suitable for portable boards. The “58” denotes a specific fixed output variant within the TPS70158 family. For exact output voltage, input range, dropout, and protection specs, consult the TI datasheet for TPS70158PWP. Common applications: microcontroller power rails, wearables, wireless sensors, and other battery-powered electronics.

Features

TPS70158PWP features (highlights):
- Ultra-low quiescent current with low shutdown current
- Enable pin to turn regulator on/off
- Fixed-output options and adjustable version via external resistors
- Wide input range (suitable for low-voltage supplies)
- Output current capability (up to ~150 mA class)
- Low dropout with good line/load regulation and fast transient response
- Overcurrent protection and thermal/shutdown safeguards
- Stable with ceramic capacitors (low ESR)
- Small footprint PWP package (RoHS-compliant)

Package

8-pin VSSOP (SOP-8) package.

Pinout

8 pins. It is a fixed-output low-dropout regulator (LDO) with enable (EN). In this package, pins include VIN, VOUT, GND, EN, and the remaining pins are typically no-connects. The device provides a fixed 1.58 V output.

Manufacturer

Manufacturer: Texas Instruments (TI).
Type of company: A multinational American semiconductor company that designs and manufactures analog and embedded processing integrated circuits.

Application

TPS70158PWP is a compact, low-dropout regulator. Typical application areas include: portable and battery-powered electronics needing efficient, low-noise voltage regulation; MCU/DSP and other digital IC power rails; sensors and IoT nodes; camera modules and display bias networks; USB peripherals and accessories; automotive and industrial electronics requiring a small form factor with clean supply and good transient response.

Equivalent

TPS70158PWP is TI’s ultra-low-quiescent LDO with a fixed 1.58 V output in a PWP package. There isn’t a direct one-for-one cross reference for exactly 1.58 V. Closest substitutes are fixed 1.5–1.8 V LDOs or adjustable LDOs that can be set to 1.58 V. For exact equivalents, use TI’s Cross-Reference tool or provide your required Iout, input/output range, and package so I can suggest closest matches from Analog Devices, ON Semiconductor, ST, etc.
