TEXAS INSTRUMENTS  LP3856ES-1.8  固定电压稳压器, LDO, 2.5V至7V, 390mV压差, 1.8V输出, 3A输出, TO-263-5

The is a 1.8V 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. The dropout voltage is typically 39mV at 300mA load current and 390mV at 3A load current. Ground pin current is typically 4mA at 3A load current.
