Partname: | LP3856-ADJ |
Description: | 3A Fast Response Ultra Low Dropout Linear Regulators |
Manufacturer: | National Semiconductor |
Datasheet: | PDF (744K). Click here to download *) |
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. |
