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. The LT3063 features an NMOS pull-down that discharges the output if SHDN or IN is driven low.
