TPS7A9401DSCR Description

Short technical summary and product information.

The TPS7A9401DSCR from Texas Instruments is a high-performance 1-A low-dropout (LDO) linear voltage regulator designed for applications requiring ultra-low noise and high power-supply ripple rejection (PSRR).

 

This device offers an adjustable output voltage ranging from 0 V to 5.5 V, with a wide input voltage range of 1.7 V to 5.7 V. Key electrical characteristics include an ultra-low output noise of 0.46 μVRMS (typ, 10 Hz to 100 kHz) and high PSRR values, such as 110 dB at 1 kHz and 50 dB at 1 MHz. The accuracy over line, load, and temperature is maintained at 1%, with a typical dropout voltage of 150 mV at 1 A.

 

Features such as programmable current limit, enable, power good, and soft start provide enhanced control. The TPS7A9401DSCR is housed in a 10-pin WSON (3x3 mm) package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ).

 

This LDO regulator is well-suited for sensitive analog circuits, macro remote radio units (RRU), outdoor backhaul units, active antenna systems, ultrasound scanners, and lab instrumentation.
