TPS77533PWP TI LDO Regulator | 20-HTSSOP | 3.3V Output, 500mA

Product Overview

The TPS77533PWP from Texas Instruments is a low-dropout (LDO) voltage regulator designed to deliver a fixed 3.3V output with a maximum current of 500mA. Housed in a 20-pin HTSSOP (PowerPAD) package, this device offers excellent thermal performance and is ideal for space-constrained applications requiring high efficiency and low noise. The TPS77533PWP features a dropout voltage of typically 169mV at full load, making it suitable for battery-powered systems. It includes an enable pin for power sequencing and a power-good output for system monitoring.
