TPS728180285YZUT TI LDO Regulator | 5-DSBGA | 1.8V/2.85V, 200mA

Product Overview

The TPS728180285YZUT from Texas Instruments is a dual-output, low-dropout (LDO) voltage regulator designed for space-constrained applications. Housed in a compact 5-pin DSBGA package (0.9mm x 1.3mm), it provides two fixed output voltages: 1.8V and 2.85V, each capable of delivering up to 200mA. With a low dropout voltage of typically 130mV at 200mA, it ensures efficient operation even when the input voltage is close to the output. The device features a low quiescent current of 40µA (typical) and offers excellent line and load transient response, making it ideal for powering sensitive analog and digital circuits in portable and battery-powered devices.
