The LT®3063 is a micropower, low dropout (LDO) linear regulator that operates over a 1.6V to 45V supply range. The device supplies 200mA of output current with a typical dropout voltage of 300mV. A single external capacitor provides programmable low noise reference performance and outputsoft-startfunctionality.The LT3063’s quiescent currentismerely 45μA andprovidesfasttransientresponse with a minimum 3.3μ F output capacitor. In shutdown, quiescent current is less than 3μA and the reference soft start capacitor is reset.
