Micropower Regulators for Battery Supply circuits

Posted on Mar 17, 2013

Three new linear regulators simplify the design of batteryoperated equipment. The LT®1521 is a 300mA, positive low dropout regulator with micropower quiescent current and shutdown. The LT1175 is a 500mA negative complement with adjustable current limit. A third product, the LT1118, has the unique capability of maintaining output regulation while sourcing or sinking load current.

The LT1521 contains all of the features associated with battery-operated applications. In designs where memory must be powered continuously, the LT1521s 12mA quiescent current eliminates the need for a separate micropower backup supply. In shu
