TPS70258PWP TI Dual-Output LDO Regulator | 20-HTSSOP | 3.3V/2.5V, 500mA

Product Overview

The TPS70258PWP from Texas Instruments is a dual-output low-dropout (LDO) voltage regulator designed for applications requiring two independent regulated voltages. Housed in a 20-pin HTSSOP (PWP) package, it delivers up to 500 mA per output with a dropout voltage as low as 170 mV at full load. The device integrates a power-on reset (POR) circuit with a programmable delay, making it ideal for powering DSPs, FPGAs, and microcontrollers in systems that demand precise sequencing and monitoring.

Detailed Technical Specifications

Key Features
