General Description
The LP3961/LP3964 series of fast ultra low-dropout linear regulators operate from a +2.5V to +7.0V input supply. 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/LP3964 are developed on a CMOS process which allows low quiescent current operation independent of output load current. This CMOS process also allows the LP3961/LP3964 to operate under extremely low dropout conditions.
Dropout Voltage: Ultra low dropout voltage; typically 24mV at 80mA load current and 240mV at 800mA load current.
Ground Pin Current: Typically 4mA at 800mA load current.
Shutdown Mode: Typically 15µA quiescent current when the shutdown pin is pulled low.
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 1.2V to 5.0V and adjustable (LP3964), with a guaranteed accuracy of ±1.5% at room temperature, and ±3.0% over all conditions (varying line, load, and temperature).

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR.
The Long Term Failure Rates were calculated
at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress
temperature of 150°C to an application temperature of 55°C.
