Overview
The AP1115AY25G-13 is a discontinued low dropout positive fixed-mode regulator manufactured by Diodes Incorporated. It provides a fixed 2.5V output with a maximum continuous current capability of 0.6A. The device supports an input voltage range up to 18V and maintains regulation with a maximum dropout voltage of 1.3V at full load. It operates within a junction temperature range of 0°C to +125°C and utilizes a SOT-89-3 surface-mount package.
Feature Summary
- Integrated thermal shutdown and output current limiting for robust protection
- Fast transient response and good noise rejection characteristics
- RoHS compliant lead-free packaging in green molding compound
Applications
- Low-voltage IC applications such as high-speed bus termination
- Low-current logic supply circuits
- VGA cards and PC peripherals
- Communication equipment power management
Procurement Notes
This component is officially marked as obsolete and discontinued by the manufacturer. No alternate part numbers are available from Diodes Incorporated. Procurement must rely on existing surplus inventory or secondary market channels, as new production units are no longer manufactured or distributed through standard supply chains.
Selection Notes
Designers requiring this specific 2.5V fixed output should note that the AP1115 series has been replaced by newer product lines. Verification of equivalent performance parameters, specifically dropout voltage and current limits, is necessary when evaluating alternative regulators. Package compatibility and pinout differences between legacy and replacement devices must be assessed during the transition.
Part Context
The AP1115 series consists of 0.6A low dropout positive adjustable or fixed-mode regulators designed for well-regulated supplies in low-voltage IC applications. The family includes various fixed output voltages ranging from 1.5V to 5.0V, as well as an adjustable version. These devices are intended for use in scenarios requiring efficient power conversion with minimal heat dissipation.
Replacement Considerations
Diodes Incorporated explicitly states there is no alternate part for the AP1115 series. Designers must identify functional equivalents from other manufacturers or newer internal product families that match the 0.6A current rating, 2.5V fixed output, and SOT-89-3 package constraints.
FAQ
What is the maximum dropout voltage for the AP1115AY25G-13?
The maximum dropout voltage is guaranteed to be less than 1.3V at the full load current of 0.6A.
Is the AP1115AY25G-13 currently in production?
No, the AP1115 series is officially obsolete and discontinued by Diodes Incorporated.
What package type does the AP1115AY25G-13 use?
It uses a SOT-89-3 surface-mount package with a lead-free, green molding compound.
