Description

General part information

LP3964 Series

The LP396x series of fast ultra-low-dropout linear regulators operate from a 2.5-V to 7-V input supply. A wide range of preset output voltage options are available. These ultra-low dropout linear regulators respond very fast to step changes in load which makes them suitable for low-voltage microprocessor applications. The LP3961 and LP3964 are developed on a CMOS process which allows low quiescent current operation independent of output load current, as well as operation under extremely low dropout conditions.

Dropout Voltage:Ultra-low dropout voltage; typically 24 mV at 80-mA load current and 240 mV at 800-mA load current.

Ground Pin Current:Typically 4 mA at 800-mA load current.
