AP7217A

3.3V 600mA CMOS LDO

AP7217A Rev. 3 1 of 10 OCTOBER 2009

DS31423 www.diodes.com © Diodes Incorporated

• Very Low Dropout Voltage

• Low Current Consumption: Typ. 50µA

• Output Voltage: 3.3V

• Guaranteed 600mA (min) Output

• Input Range up to 5.5V

• Current Limiting

• Stability with Low ESR Capacitors

• Thermal shutdown Protection

• Low Temperature Coefficient

• SOP-8L and SOP-8L-EP: Available in “Green” Molding

Compound (No Br, Sb)

• Lead Free Finish/ RoHS Compliant (Note 1)

The AP7217A low-dropout linear regulator operates from a 3.3V

to 5.5V supply and delivers a guaranteed 600mA (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 200ms (TYP) after output voltage reaches

regulation.

The space-saving SOP-8L and SOP-8L-EP packages are

suitable for “pocket” and hand-held application.

• HD/ Blue Ray DVD & MP3/4 Players

• CD and MP3 Players

• Cellular and PCS Phones

• Digital Still Camera

• Hand-Held Computers

VIN 1.6V VDOUT EN VROUT Application Note Input Capacitor A 1µF ceramic capacitor is recommended to connect between IN and GND pins to decouple input power supply glitch and noise. The amount of the capacitance may be increased without limit. A lower ESR (Equivalent Series Resistance) capacitor allows the use of less capacitance, while higher ESR type requires more capacitance.
