• 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
