The APL5708R series are micropower, low dropout linear regulators, which operate from 2.7V to 6V input voltage and deliver up to 700mA. Typical dropout voltage is only 700mV at 700mA loading. Designed for use in battery-powered system, the low 60A quiescent current makes it an ideal choice. Design with an internal P-channel MOSFET pass transistor, the APL5708R maintain a low supply current, independent of the load current and dropout voltage. Other features include thermal-shutdown protection, current limit protection to ensure specified output current and controlled short-circuit current. The APL5708R regulators come in a miniature SOT-223 package.
