TPS70402PWPR TI Dual-Output LDO Regulator | 24-HTSSOP | 3.3V/2.5V, 1A/2A

Product Overview

The TPS70402PWPR from Texas Instruments is a dual-output low-dropout (LDO) voltage regulator designed for applications requiring two independent regulated voltages. Housed in a compact 24-HTSSOP package, this device delivers output 1 (VO1) adjustable from 1.22V to 5.5V with a 1A current capability, and output 2 (VO2) adjustable from 1.22V to 5.5V with a 2A current capability. The TPS70402PWPR features low dropout voltage (typically 200mV at 1A for VO1 and 300mV at 2A for VO2), high accuracy (±1%), and excellent transient response. It includes enable pins, undervoltage lockout (UVLO), and thermal shutdown protection, making it ideal for powering sensitive loads in industrial, automotive, and telecommunications systems.
