APL5601/2是低压降(low dropout)的线性降压转换器,其输入电压可操作在2.9V至6V电压范围之间,且输出电流可高达600mA﹔一般来说当输出电流为600mA时,压降为220mV。APL5601/2所需的静态电流仅需140μA,非常适合电池系统上的应用。APL5601/2的输出电容仅需2.2μF,即可保持系统稳定。APL5601/2内建过电流保护(current limit) ,短路电流保护(short circuit current limit)与过温保护(OTP)以防止IC烧毁。APL5601/2可使用SOT-23,SOT-89与SOT-223包装,对于解省电路板空间有很大的帮助。
The APL5601/5602 family of low-power and low dropout linear regulators which operate from 2.9V to 6V input voltage and deliver up to 600mA output current. Typical dropout voltage is only 220mV (typical) at 600mA output. The APL5601/5602 regulators with low 140A quiescent current are ideal for battery-powered system appliances. The APL5601/5602 regulators are stable with a 2.2F ceramic capacitor. The features of current limit, short circuit current limit, and over-temperature protection protect the device against current over loads and over temperature. The APL5601/5602 regulators come
in SOT-23, SOT-89, and SOT-223 packages.
