• Battery powered portable electronics

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance and lead-free status against manufacturer specifications. Ensure ordering suffix matches required package type and tape/reel quantity. Validate datasheet revision prior to integration.

Selection Notes

Select this regulator for designs requiring precise 2.8V regulation from single-cell lithium sources. Evaluate thermal dissipation requirements based on ambient temperature and PCB copper area. Consider the SOT353 package constraints for space-limited layouts. Verify input capacitor stability requirements for loop compensation.

Part Context

This component belongs to the AP7115 family of low dropout linear regulators designed for portable electronics. It serves as a legacy solution within Diodes Incorporated's portfolio, offering fixed output voltages ranging from 1.0V to 3.5V. The series emphasizes low quiescent current and robust protection features for mobile device power management.

Replacement Considerations

Datasheet explicitly recommends using AP7315 instead of AP7115 for new designs.
