TPS70145PWP TI Dual-Output LDO Regulator | 20-HTSSOP | 3.3V/1.8V, 500mA

Product Overview

The TPS70145PWP 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 with PowerPAD for enhanced thermal performance, this device delivers up to 500 mA per output with a dropout voltage as low as 170 mV at full load. It features a wide input voltage range of 2.7 V to 6 V, making it suitable for battery-powered and industrial systems. The TPS70145PWP integrates a power-on reset (POR) function with programmable delay, ensuring proper system initialization.
