LT3014ES5#PBF

LINEAR TECHNOLOGY  LT3014ES5#PBF  电压稳压器, LDO, 可调, 3V至80V输入, 350mV压差, 1.22V至60V/20mA输出, SOT-23-5

The is a 20mA low dropout micropower Linear Regulator capable of supplying 20mA output current with a dropout voltage of 350mV. Designed for use in battery-powered or high voltage systems, the low quiescent current 7µA operating and 1µA in shutdown makes it an ideal choice. Quiescent current is also well controlled in dropout. Other features of the LT3014 include the ability to operate with very small output capacitors. The regulator is stable with only 0.47µF on the output while older devices require between 10 and 100µF for stability. Small ceramic capacitors can be used without the necessary addition of ESR as is common with other regulators. Internal protection circuitry includes reverse-battery protection, current limiting, thermal limiting and reverse current protection. The device is available with an adjustable output with a 1.22V reference voltage.
