AP1115AY15L-13

Overview

The AP1115AY15L-13 is a low dropout positive fixed-mode regulator manufactured by Diodes Incorporated. It provides a fixed output voltage of 1.5V with an output current capability of 0.6A. The device operates with an input supply voltage up to 18V and maintains a maximum dropout voltage of 1.3V at full load current. It features built-in thermal shutdown and output current limiting for protection. The component is housed in a lead-free SOT89-3L package.

Feature Summary

• Provides stable power regulation for low-voltage integrated circuits
• Includes internal circuitry for output current limiting and thermal shutdown
• Delivers fast transient response to load changes
• Offers good noise rejection characteristics

Applications

• High-speed bus termination
• Low-current logic supply
• PC peripheral devices
• Communication equipment

Procurement Notes

This specific part number is officially marked as obsolete and discontinued by the manufacturer. No alternate replacement parts are available from Diodes Incorporated. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors, as availability is limited and subject to depletion without future replenishment.

Selection Notes

Select this component only if the design requires a fixed 1.5V output at up to 0.6A within an 18V input range. Verify that the SOT89-3L package fits the board layout constraints. Ensure the application does not require life support or critical safety functions, as these uses are explicitly prohibited by the manufacturer's warranty terms.

Part Context

The AP1115 series consists of low dropout positive regulators designed for applications requiring well-regulated supplies. This specific variant belongs to the fixed-output family, distinct from the adjustable mode versions. It is engineered to handle significant input-to-output differentials while maintaining regulation under full load conditions.

Replacement Considerations

No alternate part numbers are confirmed by the manufacturer. The product line is discontinued with no direct replacements provided.
