TPS7A3901DSCT Description

Short technical summary and product information.

The TPS7A3901DSCT from Texas Instruments is a versatile dual-channel low-dropout (LDO) voltage regulator designed for positive and negative voltage regulation.

 

This device features an adjustable output voltage range, supporting positive outputs from 1.2V to 30V and negative outputs from -30V to 0V. Each channel can deliver up to 150mA of output current. Key electrical characteristics include a wide input voltage range of ±3.3V to ±33V, a typical dropout voltage of 0.5V at 150mA, and a high power-supply rejection ratio (PSRR) of 69dB at 120Hz. The output voltage noise is typically 21µVRMS from 10Hz to 100kHz.

 

Designed for ease of use, the TPS7A3901DSCT includes features such as a single positive-logic enable pin and adjustable soft-start for in-rush current control. It also offers protection features like over-temperature shutdown and under-voltage lockout (UVLO).

 

The regulator is housed in a 10-pin WSON package with a 3mm x 3mm footprint and an exposed pad for improved thermal performance. The mounting type is surface mount, and it operates within a temperature range of -55°C to 150°C.
