Current live pairing is not a normal replacement path. MIC29150-12WU is a 12 V, 1.5 A TO-263 regulator, while NCP1117ST25T3G is a 2.5 V, 1.0 A SOT-223 1117-family regulator. This can only be kept as a redesign-level similar reference, not as a functional alternative.
NCP1117ST25T3G
1.0 A Low-Dropout Positive Fixed and Adjustable Voltage Regulators The NCP1117 series are low dropout positive voltage regulators that are capable of providing an output current that is in excess of 1.0 A with a maximum dropout voltage of 1.2 V at 800 mA over temperature. This series contains eight fixed output voltages of 1.5 V, 1.8 V, 2.0 V, 2.5 V, 2.85 V, 3.3 V, 5.0 V, and 12 V that have no minimum load requirement to maintain regulation. Also included is an adjustable output version that can be programmed from 1.25 V to 18.8 V with two external resistors. On chip trimming adjusts the reference/output voltage to within ±1.0% accuracy. Internal protection features consist of output current limiting, safe operating area compensation, and thermal shutdown. The NCP1117 series can operate with up to 20 V input. Devices are available in SOT−223 and DPAK packages.

This page is designed for first-pass shortlist work. Treat the candidates below as engineering starting points, then verify footprint compatibility, electrical limits, lifecycle timing, compliance requirements, and qualification scope before approving a BOM change. For official sample requests, full data verification, and legal warranty support, please consult through TrustCompo Inquiry Channel.
If this page helped your review work, please consider starring the project on GitHub. If you spot incorrect data, missing alternatives, or context that needs clarification, please open an issue.
Cross-reference pages are useful starting points, not automatic design approvals. Always re-check footprint, electrical limits, lifecycle timing, qualification documents, firmware implications, and supply-chain constraints before releasing a BOM change.
