Product Summary

The TPS77533PWP is a fast-transient-response 500mA low-dropout voltage regulator. The TPS77533PWP is designed to have a fast transient response and be stable with a 10-μF low ESR capacitors. This combination provides high performance at a reasonable cost. Because the TPS77533PWP behaves as a low-value resistor, the dropout voltage is very low (typically 169 mV at an output current of 500 mA 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 mA over the full range of output current, 0 mA to 500 mA). These two key specifications yield a significant improvement in operating life for battery-powered systems.
