LR6209
„ INTRODUCTION
„ FEATURE
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.
● Standby Current : Less than 0.1µA (TYP.)
● Maximum Output Current:250mA(Typ)
● Output Voltage Range:1.4V~6.0V,
(selectable in 0.1V steps)
● High Accuracy:±2%(Typ)
● Dropout Voltage:[email protected](3.0V Typ)
● Excellent Line Regulaion:0.1%/V
● High Ripple Rejection : 62dB (10kHz)
● Buit-in Chip Current Limit & Short Protect Circuit
● Static safety: [email protected]
● TC:100ppm/℃
„ APPLICATION
● Battery powered systems
● Portable instrumentations
● Reference Voltage Sources
● Radio control systems
● Portable/Palm computers
● Portable consumer equipments
