Description
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. ERROR Flag: ERROR flag goes low when the output voltage drops 10% below nominal value (for LP3961). SENSE: SENSE pin improves regulation at remote loads (for LP3964). Precision Output Voltage: Multiple output voltage options are available ranging from 1.2 V to 5 V and adjustable (LP3964), with a specified accuracy of ±1.5% at room temperature, and ±3% over all conditions (varying line, load, and temperature).
