LP3965EMPX-2.5/NOPB

低压差稳压器 1.5A Fast Ultra Low Dropout Linear Regulator 5-SOT-223 -40 to 125

DESCRIPON

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 developed 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.
