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 V
DF
.
The space-saving SOP-8L package is suitable for “pocket”
and hand-held applications.
Features
Very Low Dropout Voltage
Low Current Consumption: Typ. 50μA
Output Voltage: 3.3V
Guaranteed 500mA (min) Output
Input Range up to 5.5V
• Current Limiting
Stable with either electrolytic capacitor or low-ESR MLCC
(multi-layer ceramic capacitor) Low Temperature
Coefficient
SOP-8L: Available in “Green” Molding Compound
(No Br, Sb)
Lead Free Finish/ RoHS Compliant (Note 1)
