TPS70745PWP TI Dual-Output LDO | 20-HTSSOP | 3.3V/2.5V, 500mA

Product Overview

The TPS70745PWP from Texas Instruments is a dual-output low-dropout (LDO) voltage regulator designed for applications requiring two independent regulated voltages. It provides fixed outputs of 3.3V and 2.5V, each capable of delivering up to 500mA of load current. The device features a low dropout voltage of typically 170mV at full load, making it suitable for battery-powered and high-efficiency systems. Housed in a 20-pin HTSSOP (PowerPAD) package, it offers excellent thermal performance and a compact footprint for space-constrained designs.
