INTRODUCTION
The LR6209 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
LR6209 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.
APPLICATION
Battery powered systems
Portable instrumentations
Reference Voltage Sources
Radio control systems
Portable/Palm computers
Portable consumer equipments
