www.ti.com SNVS067H – APRIL 2000 – REVISED APRIL 2013 LP3963/LP3966 3A Fast Ultra Low Dropout Linear Regulators
Check for Samples: LP3963, LP3966 FEATURES DESCRIPTION The LP3963/LP3966 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 quickly to step changes in
load which makes them suitable for low voltage
microprocessor applications. The LP3963/LP3966 are
developed on a CMOS process which allows low
quiescent current operation independent of output
load current. This CMOS process also allows the
LP3963/LP3966 to operate under extremely low
dropout conditions. 1 2 Ultra Low Dropout Voltage
