Texas Instruments LP3853ET-3.3/NOPB The LP3853/LP3856 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 LP3853/LP3856 are developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3853/LP3856 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. ErrorFlag:Errorflag 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 1.8V to 5.0V with a ensured accuracy of ±1.5% at room temperature, and ±3.0% over all conditions (varying line, load, and temperature).
