LR6218 Series
Low Dropout Voltage
300mA CMOS LDO Regulator
INTRODUCTION
The LR6218 Series
are a group of
positive voltage regulators manufactured
by CMOS technologies with high ripple
rejection, extremely low power consump-
tion and low dropout voltage, which
provide large output currents even when
the difference of the input-output voltage is
small. Each of the LR 6218 series consists
of a high-precision voltage reference, an
error correction circuit, and a current limit-
ed output driver. Thus the series are very
suitable for the battery-powered equip-
ments, such as Portable/Palm computers,
Portable consumer equipments, industry
equipments and so on, which want to
prolong the using life of the battery.
