TPS79921YZUT TI LDO Regulator | 5-DSBGA | 200mA, 1.2V Output

Product Overview

The TPS79921YZUT from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed for space-constrained applications. Housed in a compact 5-pin DSBGA package (0.8mm x 0.8mm), it delivers up to 200mA of output current with a fixed output voltage of 1.2V. The device features ultra-low dropout voltage (typically 100mV at 200mA), high PSRR (65dB at 1kHz), and low quiescent current (40µA typical). It is optimized for noise-sensitive and battery-powered systems requiring minimal board space.
