Description

General part information

LP3856-ADJ Series

The LP3856-ADJ fast ultra low-dropout linear regulators operate from a +2.5V to +7.0V input supply. These ultra low dropout linear regulators respond very quickly to step changes in load, which makes them suitable for low voltage microprocessor applications. The LP3856-ADJ is developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3856-ADJ to operate under extremely low dropout conditions.

Dropout Voltage:Ultra low dropout voltage; typically 39mV at 300mA load current and 390mV at 3A load current.

Ground Pin Current:Typically 4mA at 3A load current.
