TPS79318YZQR TI LDO Regulator | 5-DSBGA | 200mA, Low Noise, High PSRR

Product Overview

The TPS79318YZQR from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It delivers a fixed output voltage of 1.8V with a maximum output current of 200mA. Housed in a compact 5-pin DSBGA (YZX) package, it offers excellent line and load transient response while maintaining low quiescent current. The device features a low dropout voltage of typically 120mV at full load, making it ideal for battery-powered systems. With an output noise of only 30µVrms (10Hz to 100kHz) and a power supply rejection ratio (PSRR) of 65dB at 1kHz, the TPS79318YZQR ensures clean power delivery to sensitive analog and RF circuits.
