LP3983

Micropower, Low Quiescent Current, CMOS Voltage

Regulator in micro SMD Package

General Description

Key Specifications

n Input Voltage Range

n Output Voltages

2.5 to 6.0V

1.6, 1.8, & 2.5

5mA

1µF Low ESR

1.0µA

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.

n Output Current

10dB

Performance is specified for a -40˚C to 125˚C temperature

range.

n Fast Start Up

170µs

For output voltages other than those stated and alternative

package options, please contact your local NSC sales office.
