LINEAR TECHNOLOGY LT1129CST-3.3#PBF 固定电压稳压器, LDO, 4.2V至30V, 450mV压差, 3.3V输出, 700mA输出, SOT-223-3
The is a micropower Low Dropout Regulator with Shutdown capable of supplying 700mA of output current with a dropout voltage of 400mV at maximum output. Designed for use in battery-powered systems, the low quiescent current, 50µA operating and 16µA in shutdown, make them an ideal choice. The quiescent current does not rise in dropout as it does with many other low dropout PNP regulators. Other features of the LT1129 include the ability to operate with small output capacitors. It is stable with only 3.3µF on the output while older devices require between 10 and 100µF for stability. Also the input may be connected to ground or a reverse voltage without reverse current flow from output to input. This makes the LT1129-3.3 ideal for backup power situations where the output is held high and the input is at ground or reversed. Under these conditions, only 16µA will flow from the output pin to ground.
