TPS73132DBVR

The TPS73132DBVR from Texas Instruments is a capacitor-free, NMOS-based low-dropout (LDO) linear voltage regulator. It is designed for applications requiring stable voltage regulation with an input range of 1.7 V to 5.5 V and a fixed output voltage of 3.2 V. This device can supply up to 150 mA of output current with an ultralow dropout voltage of typically 30 mV at a 150 mA load.

Key features include excellent load transient response, low noise (30 µVRMS typical), and high accuracy (0.5% initial, 1% overall). The regulator also provides protection features such as thermal shutdown and foldback current limit. Its low quiescent current, less than 1 µA in shutdown mode, makes it suitable for portable and battery-powered devices.

The TPS73132DBVR utilizes an advanced BiCMOS process and an NMOS pass element, enabling stability with output capacitors of all types, including operation without an output capacitor. It offers high reverse blockage and low reverse current. The device is supplied in a SOT-23-5 surface-mount package, measuring 2.90 mm x 1.60 mm, facilitating compact PCB designs.

Applications for this LDO include smart grid and energy systems, building automation, set-top boxes, medical equipment, test and measurement devices, point-of-sale terminals, and wireless infrastructure, where stable and efficient power management is critical.
