Description

The LT®1175 is a negative micropower low dropout regulator. It features 45µA quiescent current, dropping to 10µA in shutdown. A new reference amplifier topology gives precision DC characteristics along with the ability to maintain good loop stability with an extremely wide range of output capacitors. Very low dropout voltage and high efficiency are obtained with a unique power transistor anti-saturation design. Adjustable and fixed 5V versions are available.
