TPS7A3901DSCR Description

Short technical summary and product information.

The Texas Instruments TPS7A3901DSCR is a dual, monolithic, high-PSRR, positive and negative low-dropout (LDO) voltage regulator. It is capable of sourcing and sinking up to 150mA of current per channel.

 

Key electrical specifications include a wide input voltage range of ±3.3V to ±33V and adjustable output voltage ranges from 1.2V to 30V for positive outputs and -30V to 0V for negative outputs. It features a high power-supply rejection ratio (PSRR) of 69dB at 120Hz and low output voltage noise of 21µVRMS (10Hz–100kHz).

 

This LDO regulator is designed for surface mount applications and comes in a 10-WSON (3x3) package. It includes control features such as current limit, enable, and soft start, along with protection features like over temperature and under voltage lockout (UVLO).

 

The operating temperature range for the TPS7A3901DSCR is -40°C to +125°C (TJ), with a typical thermal resistance of 44.4°C/W.
