General Description

The AP7217 low-dropout linear regulator operates from a 3.3V to 5.5V supply and delivers a guaranteed 500mA (min) continuous load current.

The high-accuracy output voltage is preset to an internally trimmed voltage. An active-low open-drain reset output remains asserted for at least 20ms (TYP) after output voltage reaches VDF.

The space-saving SOP-8L package is suitable for “pocket” and hand-held applications.
