TPS79428DGNT Description

Short technical summary and product information.

The Texas Instruments TPS79428DGNT is a 250mA low-dropout (LDO) linear voltage regulator. It provides a fixed 2.8V output voltage and is designed for applications requiring low noise and high power-supply rejection ratio (PSRR).

 

Key electrical specifications include an input voltage range of 2.7V to 5.5V and a maximum output current of 250mA. The device exhibits a typical dropout voltage of 155mV at 250mA and a low quiescent current of 170µA. It also features high PSRR, rated at 60dB at 10kHz, and ultralow noise performance of 32µVrms.

 

The TPS79428DGNT is stable with a minimum load capacitance of 2.2µF. It includes enable control and protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

This regulator is available in an 8-HVSSOP package, suitable for surface mount applications. The operating temperature range is -40°C to 125°C.
