TPS793285YZQR TI LDO Regulator | 5-DSBGA | 2.85V Output, 200mA, Low Noise

Product Overview

The TPS793285YZQR 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 2.85V with a maximum output current of 200mA. Housed in a compact 5-pin DSBGA package (0.9mm x 1.3mm), this device offers excellent line and load regulation, making it ideal for portable and space-constrained designs. The TPS793285YZQR features a low dropout voltage of typically 120mV at full load, ensuring efficient operation even with small input-to-output voltage differentials. Its ultra-low output noise (30µVRMS typical) and high power supply rejection ratio (PSRR) of 65dB at 1kHz make it suitable for RF, audio, and precision analog circuits.
