本稳压器电路允许输入-输出差低至0.1V。这样低的压降,可使你所设计的产品中使用最少量的电池单元。此电路提供5V的稳压输出并能给出最大500mA电流。由下式可选择R_1和R_2以产生其它输出电压: V_(OUT)=[(R_1/R_2)+1]V_(REF) 晶体Q_1是一大功率PNP器件,当其工作在
This regulator circuit allows input-output differential as low as 0.1V. This low pressure drop allows you to design the product to use the smallest battery cells. This circuit provides 5V regulated output and can give a maximum 500mA current. R_1 and R_2 are chosen to produce the other output voltages as follows: V OUT = [(R_1 / R_2) +1] V_ (REF) Crystal Q_1 is a high-power PNP device that operates at
