LP3874EMP-5.0/NOPB

The LP3871 and LP3874 series of fast ultra-low-dropout linear regulators operate from a 2.5-V to 7-V 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 devices are developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3871 and LP3874 to operate under extremely low dropout conditions.Dropout Voltage: Ultra-low-dropout voltage; typically 24 mV at 80-mA load current and 240 mV at 0.8-A load current.Ground Pin Current: Typically 6 mA at 0.8-A load current.Shutdown Mode: Typically 10-nA quiescent current when the SD pin is pulled low.ERROR Flag: ERROR flag goes low when the output voltage drops 10% below nominal value.SENSE: SENSE pin improves regulation at remote loads.Precision Output Voltage: Multiple output voltage options are available ranging from 1.8 V to 5 V with a ensured accuracy of ±1.5% at room temperature, and ±3% over all conditions (varying line, load, and temperature).
