LP3876-ADJ数据手册TI中文资料规格书

描述 Description

The LP3876-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 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.
