LP3983
Micropower, Low Quiescent Current, CMOS Voltage
Regulator in micro SMD Package
General Description
The LP3983 is a fixed voltage low current regulator.
The LP3983 is ideally suited to standby type applications in
battery powered equipment, it allows the lifetime of the bat-
tery to be maximized. The device can be controlled via an
Enable(disable) control and can thus be used by the system
to further extend the battery lifetime by reducing the power
consumption to virtually zero.
Performance is specified for a -40˚C to 125˚C temperature
range.
For output voltages other than those stated and alternative
package options, please contact your local NSC sales office.
