LTP3570 is is a high voltage (up to 40 V) ultra-low quiescent current low dropout voltage regulator(LDO) manufactured in CMOS processes. It can deliver up to 500 mA of current while consuming only 2.5 μA of quiescent current. It consists of a reference voltage generator, an error amplifier, a current fold back circuit, and a phase compensation circuit plus a driver transistor. The LTP3570 is designed specifically for applications where very-low IQ is a critical parameter. This device maintains low quiescent current consumption even in dropout mode to further increase the battery life.
