TPS70345PWP TI Dual-Output LDO Regulator | 24-HTSSOP | 3.3V/1.8V, 1A/2A

Product Overview

The TPS70345PWP from Texas Instruments is a dual-output low-dropout (LDO) voltage regulator designed for applications requiring two independent regulated voltages. Housed in a 24-pin HTSSOP package, this device provides a fixed output of 3.3V (1A) and 1.8V (2A) with high accuracy and low dropout voltage. It features integrated power-good indicators, enable control, and thermal shutdown protection, making it ideal for powering mixed-signal systems in telecommunications, industrial, and automotive applications.
