AP7217 500mA CMOS LDO Description Pin Assignments The AP7217 low-dropout linear regulator operates from a ( Top View ) 3.3V to 5.5V supply and delivers a guaranteed 500mA (min) continuous load current. NC EN 1 8 The high-accuracy output voltage is preset to an internally 2 trimmed voltage. An active-low open-drain reset output VR 7 GND OUT remains asserted for at least 20ms (TYP) after output voltage AP7217 reaches V . NC 3 6 VD DF OUT The space-saving SOP-8L package is suitable for pocket V 4 5 NC IN and hand-held applications. SOP-8L Applications Features HD/ BlueRay DVD & MP3/4 Players Very Low Dropout Voltage Mobile Handsets and Smartphones Low Current Consumption: Typ. 50A Digital Still Camera Output Voltage: 3.3V Hand-Held Computers 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) Notes: 1.
