www.ti.com SNVS220E – NOVEMBER 2002 – REVISED APRIL 2013 LP3873/LP3876 3A Fast Ultra Low Dropout Linear Regulators
Check for Samples: LP3873, LP3876 FEATURES DESCRIPTION The LP3873/LP3876 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 LP3873/LP3876 are
developed on a CMOS process which allows low
quiescent current operation independent of output
load current. This CMOS process also allows the
LP3873/LP3876 to operate under extremely low
dropout conditions. 1 2 Ultra Low Dropout Voltage
