LT1121HVCS8

LDO Regulator Pos 3.75V to 30V 0.15A 8Pin SOIC N

DESCRIPTION

The LT®1121/LT1121-3.3/LT1121-5 are micropower low dropout regulators with shutdown. These devices are capable of supplying 150mA of output current with a dropout

voltage of 0.4V. Designed for use in battery-powered systems, the low quiescent 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.
