Overview
The TPS76833QPWPR is a 1-A, 10-V, low-dropout voltage regulator produced by Texas Instruments. This device is part of the TPS768xxQ family, known for its fast transient response and stability with 10 µF capacitors, providing high performance at a reasonable cost. The regulator features a PMOS pass element, which results in a very low dropout voltage and ultralow quiescent current, making it ideal for battery-powered systems. It also includes a shutdown mode, thermal shutdown protection, and an open-drain power good output.
