www.ti.com SNVS173G – FEBRUARY 2003 – REVISED APRIL 2013 LP3853/LP3856 3A Fast Response Ultra Low Dropout Linear Regulators
Check for Samples: LP3853, LP3856 FEATURES DESCRIPTION The LP3853/LP3856 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 LP3853/LP3856 are
developed on a CMOS process which allows low
quiescent current operation independent of output
load current. This CMOS process also allows the
LP3853/LP3856 to operate under extremely low
dropout conditions. 1 2 Ultra Low Dropout Voltage
