1 / 19 page Low I Q, Low Dropout 300mA Fixed Voltage Regulator Copyright ANPEC Electronics Corp. Rev. B.1 - Mar., 2004 APL5301/2 www.anpec.com.tw 1 ANPEC reserves the right to make changes to improve reliability or manufacturability without notice, and advise customers to obtain the latest version of relevant information to verify before placing orders. Features The APL5301/2 series are micropower, low noise, low dropout linear regulators, which operate from 3V to 6V input voltage and deliver up to 300mA. Typical dropout voltage is only 260mV at 300mA loading. De- signed for use in battery-powered system, the low 50uA quiescent current makes it an ideal choice. Design with an internal P-channel MOSFET pass transistor, the APL5301/2 maintain a low supply current, inde- pendent of the load current and dropout voltage. Other features include reverse current protection, ther- mal-shutdown protection, current limit protection to ensure specified output current and controlled short- circuit current. The APL5301/2 regulators come in a miniature SOP-8, SOT-23, SOT-23-5, SOT-89 and SOT-89-5 packages.
