The LP3962/LP3965 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 LP3962/LP3965 are developed on a CMOS process which
allows low quiescent current operation independent of output load current. This CMOS process also
allows the LP3962/LP3965 to operate under extremely low dropout conditions.
Dropout Voltage: Ultra low dropout voltage; typically
38mV at 150mA load current and 380mV at 1.5A load current.
Ground Pin Current: Typically 5mA at 1.5A load
Shutdown Mode: Typically 15µA quiescent current when the
shutdown pin is pulled low.
Error flag goes low when the output voltage drops 10% below nominal value
SENSE: Sense pin improves regulation at remote loads.
Precision Output Voltage: Multiple output voltage
options are available ranging from 1.2V to 5.0V and adjustable (LP3965), with a specified accuracy
of ±1.5% at room temperature, and ±3.0% over all conditions (varying line, load, and
