DESCRIPTION
This device is designed to have an ultralow quiescent current and be stable with a 4.7-µF capacitor. 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 230 m V at an output current of 250 m A for the TPS76650) 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 35 µA over the full range of output current, 0 m A to 250 m A). These...
