TPS77501-Q1
description
The TPS775xx and TPS776xx devices are designed to have a fast transient response and be stable with a 10-µF low ESR capacitors. This bination provides high performance at a reasonable cost.

Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 169 m V at an output current of 500 m A for the TPS77x33) and is directly proportional to the output current. Additionally, since the PMOS pass element is a voltage-driven device, the quiescent current is very low and independent of output loading (typically 85 µA over the full range of output...
