TPS73HD301PWP TI Linear Regulator | 28-HTSSOP | Dual Output, 3.3V/1.8V

Product Overview

The TPS73HD301PWP from Texas Instruments is a dual-output low-dropout (LDO) linear regulator designed for applications requiring high performance and low noise. It provides two regulated outputs: a fixed 3.3V output and an adjustable output (1.2V to 9.75V), with a maximum output current of 750mA per channel. Housed in a 28-pin HTSSOP package with PowerPAD for enhanced thermal dissipation, this device offers excellent line and load regulation, making it ideal for powering sensitive analog and digital circuits in industrial, automotive, and telecommunications systems.
