TPS73HD318PWPR TI Dual Output LDO | 28-HTSSOP | 3.3V/1.8V, 750mA/350mA

Product Overview

The TPS73HD318PWPR from Texas Instruments is a dual-output low-dropout (LDO) voltage regulator designed for applications requiring two independent regulated voltages. It provides a fixed 3.3V output at 750mA and a fixed 1.8V output at 350mA, with high accuracy and low dropout voltage. The device is housed in a 28-pin HTSSOP package with PowerPAD for enhanced thermal performance. It features enable pins for each output, undervoltage lockout (UVLO), overcurrent protection, and thermal shutdown, making it suitable for powering DSPs, FPGAs, and other mixed-voltage systems.
