LP3873/LP3876 3A Fast Ultra Low Dropout Linear Regulators
General Description
The LP3873/LP3876 series of fast ultra low-dropout linear regulators operate from a +2.5V to +7.0V input supply.

Wide range of preset output voltage options are available. These ultra low dropout linear regulators respond very quickly to step changes in load, which makes them suitable for low voltage microprocessor applications. The LP3873/LP3876 are developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3873/LP3876 to operate under extremely low dropout conditions. Dropout Voltage: Ultra low dropout voltage; typically 80mV at 300mA load current and 800mV at 3A load current. Ground Pin Current: Typically 6mA at 3A load current. Shutdown Mode: Typically 1µA quiescent current when the shutdown pin is pulled low. Error Flag: Error flag goes low when
