TPS79425DGNR Description

Short technical summary and product information.

The Texas Instruments TPS79425DGNR is a 250mA low-dropout (LDO) linear voltage regulator designed for noise-sensitive applications. It provides a fixed 2.5V output voltage and features ultralow noise (32 µVrms) and high power-supply rejection ratio (PSRR) of up to 65dB at 100Hz.

 

This regulator is stable with a small 2.2µF ceramic capacitor on the output and offers a very low dropout voltage of 155mV typical at full load. It includes an Enable (EN) pin for control and protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

The TPS79425DGNR is available in an 8-HVSSOP package, suitable for surface mounting. Its fast start-up time and excellent load and line transient response make it ideal for RF electronics, portable devices, and other applications requiring clean power.

 

Key electrical characteristics include a minimum input voltage of 2.7V and a maximum of 5.5V, with a maximum output current of 250mA. The typical quiescent current is 170µA. The operating temperature range is -40°C to 125°C.
