APL5508
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
60µA 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.
