TPS70148PWPR TI Dual-Output LDO Regulator | 20-HTSSOP | 3.3V/1.8V, 500mA

Product Overview

The TPS70148PWPR 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 separate enable pins, power-good indicators, and overcurrent/thermal protection, making it ideal for powering DSPs, FPGAs, and mixed-signal systems in industrial and automotive environments.
