LP3983
Micropower, Low Quiescent Current, CMOS Voltage
Regulator in micro SMD Package
General DescriptionThe LP3983isa fixed voltage low current regulator.
The LP3983is ideally suitedto standby type applicationsin
battery powered equipment,it allowsthe lifetimeofthe bat-
terytobe maximized. The device canbe controlledviaan
Enable(disable) control and can thusbe usedbythe system further extend the battery lifetimeby reducing the power
consumptionto virtually zero.
Performanceis specifiedfora -40˚Cto 125˚C temperature
range.
For output voltages other than those stated and alternative
package options, please contact your local NSC sales office.
