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 battery 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.
