LP3874-ADJ (ACTIVE)

0.8A Fast Ultra Low Dropout Linear Regulators

 

Description

The LP3874-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 LP3874-ADJ is developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3874-ADJ to operate under extremely low dropout conditions.

Dropout Voltage: Ultra low dropout voltage; typically 24mV at 80mA load current and 240mV at 0.8A load current.

Ground Pin Current: Typically 6mA at 0.8A 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.
