LP3856ET-ADJ

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.Shutdown Mode: Typically 10nA quiescent current when the shutdown pin is pulled low.Adjustable Output Voltage: The output voltage may be programmed via two external resistors.
