General Description
The APL5508/9/R series are micropower, low dropout
linear regulators, which operate from 2.7V to 6V input
voltage and deliver up to 560mA. Typical dropout
voltage is only 600mV at 560mA loading. Designed
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 specified output
current and controlled short-circuit current. The
APL5508/9/R regulators come in a miniature SOT-23,
SOT-89 and SOT-223 packages.
