LP3871EMP-3.3

The LP3871EMP-3.3 is a 3.3V fixed output fast ultra-low-dropout (LDO) Linear Regulator operate from a 2.5 to 7V input supply. This device respond very quickly to step changes in load, which makes them suitable for low voltage microprocessor applications. The device is developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the device to operate under extremely low-dropout (LDO) conditions. Dropout voltage is typically 24mV at 80mA load current and 240mV at 0.8A load current. Ground pin current is typically 6mA at 0.8A load current. ERROR\ flag goes low when the output voltage drops 10% below nominal value. SENSE pin improves regulation at remote loads.
