TPS74901 Description

Short technical summary and product information.

The Texas Instruments TPS74901 is a high-performance, 3A adjustable ultra-low-dropout linear voltage regulator designed for various power management applications. It operates with an ultra-low input voltage range from 0.8V to 5.5V and offers an adjustable output voltage range from 0.8V to 3.6V. The device boasts a low dropout voltage of typically 120mV at 3A, ensuring efficient power delivery.

 

Key electrical specifications include an accuracy of 1-2% over line, load, and temperature, a typical quiescent current of 3mA, and low noise (20µVrms) with good PSRR (28dB at 100 KHz). The TPS74901 supports programmable soft-start for in-rush current control and features a power-good output for supply monitoring or sequencing.

 

This voltage regulator is stable with any output capacitor greater than or equal to 2.2µF. It is available in multiple package options, including small 3mm x 3mm VSON, 5mm x 5mm VQFN, and TO-263 packages, suitable for space-constrained designs. The operating temperature range is -40°C to 125°C.
