The Texas Instruments TPS79428DCQR is a low-noise, positive fixed 2.8V linear voltage regulator with an output current capability of 250mA. This SOT-223-6 packaged device features low quiescent current of 220µA and a low dropout voltage of 0.21V at 250mA. It offers robust protection including over current, over temperature, reverse polarity, and under voltage lockout (UVLO). The TPS79428DCQR exhibits good power supply rejection ratio (PSRR) ranging from 65dB to 40dB across the 100Hz to 100kHz frequency range. It is suitable for applications in automotive, industrial, and consumer electronics requiring stable voltage regulation. Operating temperature range is -40°C to 125°C. This component is supplied in tape and reel packaging.
