TPS74401RGRR Description

Short technical summary and product information.

The TPS74401RGRR from Texas Instruments is a high-performance, 3-A adjustable ultra-low-dropout (LDO) linear voltage regulator. Designed for applications requiring low noise and high power supply rejection ratio (PSRR), this device operates with an input voltage range from 0.8V to 5.5V and provides an adjustable output voltage from 0.8V to 3.6V.

 

Key electrical characteristics include a typical quiescent current of 3 mA, a low dropout voltage of 120 mV at 3 A, and an accuracy of 1% over line, load, and temperature. The regulator features an enable pin for control and a power-good output for monitoring supply status. It is designed to be stable with any output capacitor greater than or equal to 2.2 µF.

 

Packaged in a 20-VQFN (3.5x3.5 mm) surface-mount package, the TPS74401RGRR is suitable for space-constrained designs. The operating temperature range is -40°C to 125°C. Protection features include over current, over temperature, short circuit, and under voltage lockout (UVLO).
