TPS70158PWPG4 TI Dual-Output LDO Regulator | 20-HTSSOP | 3.3V/2.5V, 500mA

Product Overview

The TPS70158PWPG4 from Texas Instruments is a dual-output low-dropout (LDO) voltage regulator designed for applications requiring two independent regulated voltages. Housed in a 20-pin HTSSOP package, this device delivers high accuracy, low noise, and excellent transient response. Each output can supply up to 500 mA with a dropout voltage as low as 170 mV at full load. The TPS70158PWPG4 integrates a power-on reset (POR) function with programmable delay, making it ideal for powering DSPs, FPGAs, and microcontrollers in systems that demand reliable sequencing.
