LP3852/LP3855
1.5A Fast Response Ultra Low Dropout Linear
Regulators
General Description
The LP3852/LP3855 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 LP3852/LP3855
are developed on a CMOS process which allows low quies-
cent current operation independent of output load current.
This CMOS process also allows the LP3852/LP3855 to op-
erate under extremely low dropout conditions.
Dropout Voltage: Ultra low dropout voltage; typically 24mV
at 150mA load current and 240mV at 1.5A load current.
Ground Pin Current: Typically 4mA at 1.5A load current.
Shutdown Mode: Typically 10nA quiescent current when
the shutdown pin is pulled low.
Error Flag: 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 1.8V to 5.0V with a guaranteed
accuracy of ±1.5% at room temperature, and ±3.0% over all
conditions (varying line, load, and temperature).

**SD and ERROR pins must be pulled high through a 10k
Ω pull-up resistor. Connect the ERROR pin to ground if this function is not used. See Application Hints
for more information.
