Product Overview
Linear Technologies LT1121IS8-5 PMIC Voltage Regulator D/C 9743
PN: LTC1121IS8-5
8-Pin
D/C 9743
The LT®1121/LT1121-3.3/LT1121-5 are micropower low dropout regulators with shutdown. These devices are capable of supplying 150mAof output currentwith a dropout voltage of 0.4V. Designed for use in battery-powered systems, the lowquiescent current, 30µA operating and 16µA in shutdown, makes them an ideal choice. The quiescent current is well-controlled; it does not rise in dropout as it does with many other low dropout PNP regulators. OtherfeaturesoftheLT1121/LT1121-3.3/LT1121-5 include the ability to operate with very small output capacitors. They are stable with only 0.33µF on the output while most older devices require between 1µF and 100µF for stability. Small ceramic capacitors can be used, enhancing manufacturability. Also the input may be connected to ground or a reverse voltage without reverse current flow from output to input. This makes the LT1121 series ideal for backup power situationswhere 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.
