Diodes Incorporated

Footprint- and pin-function-compatible P2P replacement for the onsemi NCP1117ST25T3G (2.5 V fixed, 1.0 A LDO, SOT-223). Diodes AP1117-25 is the industry-standard 1117 family variant with the same SOT-223 pinout (pin 1=Adj/GND, pin 2=Vout, pin 3=Vin, tab=Vin), 1.3 V max dropout at 1.0 A, ±2% tolerance. Direct drop-in for designs migrating from the onsemi NCP1117 family after onsemi's 1Q2021 PDN (Last Ship 2025-04-08).

AP1117-25 is indexed here as a mapped pin-to-pin replacement for AP1117-25 with package, lifecycle, stock, MOQ, datasheet, and key attribute context for buyer review.

Cross-reference FAQ

Replacement Part Questions

Short answers for teams reviewing AP1117-25 replacement and equivalent-part options.

What is a cross-reference page for AP1117-25?

This page groups mapped replacement options for AP1117-25 so buyers and engineers can compare alternatives before requesting a quote or approving a substitute.

Does a mapped alternative mean a guaranteed drop-in replacement for AP1117-25?

Not automatically. Cross-reference mapping helps shortlist candidates, but package, electrical behavior, qualification scope, and approval rules still need to be checked before release.

Which parameters should teams compare first for AP1117-25 alternatives?

Start with package, series, key attributes, lifecycle status, stock position, datasheet access, and the mapped pin-to-pin or cross-reference note. Then confirm application-specific requirements in the datasheet and RFQ stage.

Can I request a quote for an alternative to AP1117-25?

Yes. Use the product links or RFQ actions on this page to request pricing, availability, documentation, and sourcing support for any listed alternative part.

Is AP1117-25 obsolete, and what replacement should buyers review first?

Check the lifecycle row on this page first. If buyers need a fast starting point, the strongest mapped replacement currently surfaced here is AP1117-25, followed by the other alternatives shown in the comparison table.
