Texas Instruments TPS79428DGNT is a low-noise, fixed 2.8V linear voltage regulator designed for applications requiring stable power. This device offers a 250mA output current with a low quiescent current of 220 µA, making it suitable for battery-powered systems. The TPS79428DGNT provides excellent power supply rejection ratio (PSRR) performance, ranging from 65dB to 40dB across 100Hz to 100kHz, which is critical for noise-sensitive analog circuits. Protection features include over current, over temperature, reverse polarity, and under voltage lockout (UVLO). The regulator operates from an input voltage up to 5.5V and features an enable pin for power sequencing. Its typical dropout voltage is 0.21V at 250mA. Supplied in an 8-HVSSOP package on tape and reel, this component is commonly found in portable electronics, medical devices, and automotive systems.
