Features

The APL5508/9/R series are micropower, low drop-

out linear regulators, which operate from 2.7V to 6V

input voltage and deliver up to 560mA. Typical drop-

out voltage is only 600mV at 560mA loading. De-

signed for use in battery-powered system, the low

60

µA quiescent current makes it an ideal choice.

Design with an internal P-channel MOSFET pass

transistor, the APL5508/9/R maintain a low supply

current, independent of the load current and dropout

voltage. Other features include thermal-shutdown

protection, current limit protection to ensure speci-

fied output current and controlled short-circuit current.

The APL5508/9/R regulators come in a miniature SOT-

23, SOT-89 and SOT-223 packages.
