AP7217
500mA CMOS LDO
Description
Pin Assignments
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.
