TPS731125DBVT Description

Short technical summary and product information.

The TPS731125DBVT from Texas Instruments is a 150mA, high-accuracy, ultra-low-dropout linear voltage regulator. It utilizes an NMOS pass element in a voltage-follower configuration, ensuring stability with or without output capacitors and providing excellent load transient response.

 

This regulator operates with an input voltage range of 1.7V to 5.5V and offers a typical dropout voltage of just 30mV at a 150mA load. Key electrical characteristics include low noise (30 μVRMS typical), 0.5% initial accuracy, and 1% overall accuracy over line, load, and temperature variations. It consumes less than 1µA in shutdown mode, making it suitable for portable applications.

 

Protection features include thermal shutdown and current-limit protection. The device is housed in a compact SOT-23-5 package, suitable for surface mounting. Its design makes it ideal for applications requiring stable, low-noise power, such as in smart grid, building automation, and medical equipment.
