TPS731125DBVR

The Texas Instruments TPS731125DBVR is a high-accuracy, ultra-low-dropout linear voltage regulator featuring reverse current protection and an enable function. It utilizes an NMOS pass element in a voltage-follower configuration, ensuring stability with output capacitors of all types, including operation without a capacitor.

This regulator operates with an input voltage range of 1.7V to 5.5V and provides a fixed 1.25V output at up to 150mA. It boasts an ultralow dropout voltage of 30mV typical at a 150mA load, excellent load transient response, and low output noise of 30µVRMS typical. The device also offers high reverse blockage and low ground pin current.

Key electrical characteristics include 0.5% initial accuracy and 1% overall accuracy over line, load, and temperature variations. It consumes less than 1µA maximum quiescent current in shutdown mode. Protection features include thermal shutdown and foldback current limit.

The TPS731125DBVR is available in a compact SOT-23-5 package, suitable for surface mounting. Its operating temperature range is -40°C to 125°C. This device is well-suited for applications requiring stable, low-noise power, such as portable electronics, smart grid devices, and building automation systems.
