LP3962/LP3965 1.5A Fast Ultra Low Dropout Linear Regulators
November 2004
LP3962/LP3965
1.5A Fast Ultra Low Dropout Linear Regulators
General Description
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 de-
veloped 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 current.
Shutdown Mode:
Typically 15µA quiescent current when
the shutdown pin is pulled low.
Error Flag:
Error flag goes low when the output voltage
drops 10% below nominal value (for LP3962).
SENSE:
Sense pin improves regulation at remote loads.
(For LP3965)
Precision Output Voltage:
Multiple output voltage options
are available ranging from 1.2V to 5.0V and adjustable
(LP3965), with a guaranteed accuracy of
±
1.5% at room
temperature, and
±
3.0% over all conditions (varying line,
load, and temperature).
