LP3876-ADJ

LP3876 - ADJ 3A快速超低压降线性稳压器 LP3876-ADJ 3A Fast Ultra Low Dropout Linear Regulator

The 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 LP3876-ADJ is developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3876-ADJ 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.

**Adjustable Output Voltage:** The output voltage may be programmed via two external resistors.
