AP7215-33SG-13

Overview

The AP7215-33SG-13 is a 600mA CMOS low-dropout linear regulator manufactured by Diodes Incorporated. It provides a fixed 3.3V output with an input voltage range of 3.3V to 5.5V. The device features a typical quiescent current of 50μA and a dropout voltage of 100mV at 100mA load. It includes active-low open-drain reset output, current limit protection, and short circuit protection. The component is housed in a space-saving SOP-8L package.

Feature Summary

• Integrated active-low open-drain reset output for microprocessor supervision
• Current limit and short circuit protection mechanisms
• Stable operation with electrolytic or low-ESR MLCC capacitors

Applications

• HD/Blue-Ray DVD players
• MP3/4 players
• Mobile handsets and smart phones
• 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 in the manufacturer's ordering information table. Confirm that the '-13' suffix indicates Tape & Reel packaging with a quantity of 2500 units per reel. Ensure compliance with RoHS directives and check for any applicable exemptions listed in the datasheet notes before finalizing procurement specifications.

Selection Notes

Select this component when a fixed 3.3V supply is required from a 3.3V to 5.5V input source with up to 600mA load capability. The integrated reset function simplifies system design for microprocessor applications. Consider the SOP-8L package for space-constrained portable designs. Verify thermal dissipation requirements based on the junction-to-ambient thermal resistance of 124°C/W for the selected package type.

Part Context

This part belongs to the AP7215 series of 600mA CMOS LDO regulators from Diodes Incorporated. The series offers fixed output voltages and includes supervisory functions. The SG variant specifically denotes the SOP-8L surface-mount package with lead-free finish and halogen-free molding compound, distinguishing it from other package options like SOT89-3L within the same electrical family.

FAQ

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 microprocessor.

How does the EN pin control the device?

The EN pin turns the regulator on when set high and off when pulled low. If unused, it should be tied to VIN to keep the output continuously on.
