TPS79425DCQR Description

Short technical summary and product information.

The Texas Instruments TPS79425DCQR is a 250mA low-dropout (LDO) linear voltage regulator. It provides a fixed 2.5V output voltage and is suitable for applications requiring high power-supply rejection ratio (PSRR) and low noise.

 

Key electrical characteristics include a maximum input voltage of 5.5V and a minimum input voltage of 2.7V. The device offers a low dropout voltage of 155mV at full load and a typical quiescent current of 0.17mA. Its ultralow noise performance is rated at 32 µVrms.

 

The TPS79425DCQR is stable with a minimum load capacitance of 2.2 µF ceramic capacitor on the output. It features an enable control for power management and protection features such as over current, over temperature, reverse polarity, and under voltage lockout (UVLO).

 

This regulator is available in a SOT-223-6 surface-mount package, making it suitable for compact designs. Its operating temperature range is -40°C to 125°C.
