TPS73131DBVR

The Texas Instruments TPS73131DBVR is a high-accuracy, ultra-low-dropout linear voltage regulator. It utilizes an NMOS pass element in a voltage-follower configuration, ensuring stability with various output capacitor ESR values, including operation without a capacitor.

This regulator features an input voltage range of 1.7V to 5.5V and provides a fixed 3.1V output at up to 150mA. Key electrical specifications include an ultra-low dropout voltage of 30mV at 150mA load, low noise of 30μVRMS, 0.5% initial accuracy, and 1% overall accuracy over line, load, and temperature variations. It also offers excellent load transient response and protection features such as over current, over temperature, and short circuit.

The TPS73131DBVR is designed for applications requiring low power consumption, with a maximum quiescent current of 550µA and less than 1µA in shutdown mode. It is suitable for portable applications and powering sensitive components like VCOs due to its low noise characteristics.

Packaged in a compact SOT-23-5 surface-mount package, this device is ideal for space-constrained designs. It operates within a temperature range of -40°C to 125°C.
