TPS70251PWP TI Dual-Output LDO Regulator | 20-HTSSOP | 3.3V/2.5V, 500mA

Product Overview

The TPS70251PWP is a dual-output low-dropout (LDO) voltage regulator from Texas Instruments, designed to provide two independent regulated outputs: 3.3V and 2.5V, each capable of delivering up to 500mA. Housed in a compact 20-HTSSOP package, this device offers excellent line and load regulation, low dropout voltage, and low quiescent current, making it ideal for powering sensitive analog and digital circuits in mixed-signal applications.
