Overview
The AP7217-33SG-13 is a low-dropout linear regulator manufactured by Diodes Incorporated. It operates from a 3.3V to 5.5V supply and delivers a guaranteed minimum continuous load current of 500mA. The device provides a fixed output voltage of 3.3V with an internal trim for high accuracy. It features a typical quiescent current of 50μA and standby current of 30μA. The component includes an active-low open-drain reset output that asserts for at least 20ms after the output reaches the detect fall voltage. It is housed in a space-saving SOP-8L package.
Feature Summary
- Integrated active-low open-drain reset output for power supervision
- Stable operation with both electrolytic capacitors and low-ESR MLCCs
- Built-in current limiting and short circuit protection mechanisms
Applications
- HD/BlueRay DVD players
- MP3/4 players
- Mobile handsets and smartphones
- Digital still cameras
- Hand-held computers
Procurement Notes
Verify the specific ordering suffix 'SG' corresponds to the SOP-8L package and Green molding compound as documented. Confirm RoHS compliance status and lead-free finish requirements against the latest manufacturer specifications before finalizing procurement orders.
Selection Notes
Select this component when a fixed 3.3V output is required within a 3.3V to 5.5V input range. Ensure the application demands a minimum of 500mA continuous load current. Verify that the SOP-8L package dimensions fit the PCB layout constraints and that the thermal resistance characteristics are suitable for the expected power dissipation levels.
Part Context
This part belongs to the AP7217 series of 500mA CMOS LDO regulators. It is designed for portable applications requiring small form factors. The datasheet notes that the AP2127 is not recommended for new designs and suggests using the AP7215 instead, indicating a product evolution within the manufacturer's portfolio.
Replacement Considerations
The datasheet explicitly recommends using the AP7215 as a replacement for the AP2127, but does not list direct substitutes for the AP7217-33SG-13. No public confirmed substitute part numbers are provided in the documentation.
FAQ
What is the function of the VDOUT pin?
VDOUT is an active-low open-drain reset output that remains asserted for at least 20ms (typical) after the output voltage reaches the detect fall voltage.
What type of output capacitors are stable with this regulator?
The AP7217 is stable with either electrolytic capacitors or low-ESR MLCC (multi-layer ceramic capacitor) types.
