LR6206
INTRODUCTION
The LR6206 Series
are a group of
positive voltage regulators manufactured
by CMOS technologies with high ripple
rejection,
extremely
low
power
consumption and low dropout voltage,
which provide large output currents even
when the difference of the input-output
voltage is small. Each of the CE6206
series consists of a high-precision
voltage reference, an error correction
circuit, and a current limited output
driver. Thus the series are very suitable
for the battery-powered equipments,
such as Portable/Palm computers,
Portable consumer equipments, industry
equipments and so on, which want to
prolong the using life of the battery.
