LOW DROPOUT VOLTAGE REGULATOR

120mA CMOS HIGH INPUT VOLTAGE LOW CONSUMPTION

DESCRIPTION

FEATURES

The A6151A series is a set of three-terminal middle

current low voltage regulator implemented in CMOS

technology. They can deliver 120mA output current

and allow an input voltage as high as 22V. They are

available with several fixed output voltages ranging

from 3.0V to 8.0V. CMOS technology ensures low

voltage drop and low quiescent current. Although

designed primarily as fixed voltage regulators, these

devices can be used with external components to

obtain variable voltages and currents.



Low power: 2uA (typ.)

Low voltage drop: 100mV @ I_OUT=1mA

Low temperature coefficient : ＜±100ppm/℃

High input voltage : 22V

Maximum output current : 120mA

Available in SOT-89-3 Package
