TPS73028YZQR TI LDO Regulator | 5-DSBGA | 200mA, 2.8V Output

Product Overview

The TPS73028YZQR from Texas Instruments is a low-dropout (LDO) linear voltage regulator designed for space-constrained applications. Housed in a compact 5-pin DSBGA package (0.9mm x 1.3mm), it delivers a fixed 2.8V output with up to 200mA of load current. The device features ultra-low dropout voltage (typically 120mV at 200mA) and low quiescent current (65µA typical), making it ideal for battery-powered and portable electronics. With an input voltage range of 2.7V to 5.5V, it supports a wide variety of power rails.
