TPS70458PWP TI Dual-Output LDO Regulator | 24-HTSSOP | 3.3V/2.5V, 1A

Product Overview

The TPS70458PWP from Texas Instruments is a dual-output low-dropout (LDO) voltage regulator designed for applications requiring two independent regulated voltages. Housed in a 24-HTSSOP package, it delivers up to 1A per output with excellent line and load regulation. The device features a wide input voltage range from 2.7V to 6V, making it suitable for battery-powered and industrial systems. Its low dropout voltage (typically 350mV at 1A) ensures efficient operation even when input voltage is close to the output. The TPS70458PWP includes enable pins for each output, undervoltage lockout (UVLO), and thermal shutdown protection.
