Overview
The AP7217A-33SG-13 is a fixed-output low-dropout linear regulator manufactured by Diodes Incorporated. It provides a guaranteed minimum output current of 600mA with a fixed 3.3V output voltage. The device operates from an input supply range of 3.3V to 5.5V and features a typical quiescent current of 50µA. It incorporates active-low open-drain reset functionality, thermal shutdown protection, and current limiting. The component is housed in a space-saving SOP-8L package.
Feature Summary
- Integrated active-low open-drain reset output that remains asserted for at least 200ms after regulation is reached
- Built-in thermal shutdown protection to limit power dissipation when junction temperature exceeds 150°C
- Current limiting and short circuit protection mechanisms to prevent damage during over-current conditions
Applications
- HD/Blue Ray DVD & MP3/4 Players
- Cellular and PCS Phones
- Hand-Held Computers
Procurement Notes
Verify the specific ordering suffix 'SG' corresponds to the SOP-8L package variant before procurement. Confirm RoHS compliance status and lead-free finish requirements against current manufacturing standards. Ensure the application environment does not exceed the maximum operating ambient temperature of 85°C or the absolute maximum junction temperature of 125°C.
Selection Notes
Select this component for applications requiring a compact solution with integrated system supervision. The inclusion of the VDOUT reset pin simplifies microprocessor monitoring circuits. Verify that the load current requirements do not exceed the guaranteed 600mA minimum output capability under all operating conditions.
Part Context
This part belongs to the AP7217A series of CMOS LDO regulators designed for portable electronics. The series emphasizes low dropout performance and stability with small ceramic capacitors. The SOP-8L package is specifically optimized for space-constrained handheld devices.

FAQ
How is the enable/shutdown function controlled?
The device is turned on by setting the EN pin high and turned off by pulling it low. If unused, the EN pin should be tied to the VIN pin.
What is the purpose of the VDOUT pin?
VDOUT is an active-low open-drain reset output that asserts a logic-low signal during power-up and power-down to supervise the system voltage.
