特性
78L12 具有多种保护和调节功能，确保在各种应用场景下提供稳定和安全的电源输出。
短路保护 该稳压器具备短路保护功能，能够在输出端短路时自动切断电源，防止设备损坏。
热保护（TSD） 当芯片温度超过设定值时，会触发热保护机制，减少或切断输出电流，以防止过热导致的损害。
过流保护（OCP） 在输出电流超过安全值时，过流保护会介入，限制或切断输出电流，以保护设备免受过载损害。
电源纹波抑制比（PSRR） 78L12 拥有优秀的电源纹波抑制比，达到 42dB (@120Hz)，这意味着它能够有效地抑制输入电源中的噪声和纹波，从而提供更稳定的输出电压。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
