LESHAN RADIO COMPANY, LTD. 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：160mV@100mA（3.0V Typ） ● Excellent Line Regulaion：0.1％/V ● High Ripple Rejection : 62dB (10kHz) ● Buit-in Chip Current Limit & Short Protect Circuit ● Static safety: 2KV@HBM ● TC：100ppm/℃ APPLICATION ● Battery powered systems ● Portable instrumentations ● Reference Voltage Sources ● Radio control systems ● Portable/Palm computers ● Portable consumer equipments BLOCK DIAGRAM ORDER INFORMATION 1/5 LESHAN RADIO COMPANY, LTD.
