TPS7A0328PDQNR TI LDO Regulator | 4-X2SON(1x1) | 300mA, 28V, Ultra-Low Noise

Product Overview

The TPS7A0328PDQNR from Texas Instruments is a high-performance, low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It delivers up to 300 mA output current with an ultra-low dropout voltage of typically 200 mV at full load. The device operates over a wide input voltage range from 2.2 V to 28 V, making it suitable for both battery-powered and industrial systems. Its fixed output voltage of 2.8 V is ideal for powering analog and digital circuits requiring a clean supply rail. The TPS7A0328PDQNR is offered in a compact 4-pin X2SON package (1 mm x 1 mm), enabling space-constrained designs.
