TPS79318YEQR TI LDO Regulator | 5-DSBGANANOSTAR™ | 200mA, Low Noise

Product Overview

The TPS79318YEQR from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It delivers up to 200 mA output current with a low dropout voltage of typically 120 mV at full load. The device features a fixed output voltage of 1.8 V and operates from an input voltage range of 2.7 V to 5.5 V. Housed in a compact 5-pin DSBGA NanoStar™ package (0.9 mm × 1.3 mm), it is ideal for space-constrained designs. The TPS79318YEQR offers excellent line and load regulation, low output noise (30 µVRMS typical), and high power supply rejection ratio (PSRR) of 65 dB at 1 kHz.
