Operate from 2.7V to 6V input voltage and deliver up to 900mA. Typical output noise is just 50 µV RMS with the addition of an external 0.1µF bypass capacitor in BP pin and typical dropout voltage is only 210mV at 900mA loading. Designed for use in bat- tery-powered system, the low 50 µA quiescent cur- rent makes it an ideal choice.

Other features include rev erse current protection, thermal-shutdown protection, current limit protection to ensure specified output current and con- trolled short-circuit current. The APL5901/2 regulator come in a miniature SOT-89, SOT-89-5, SOT-223, SO- 8, TO-252 and TO-252-5 packages. |
