AMS1117-3.3(GR 国睿品牌)是一款固定输出为3.3V的正电压低压降三端线性稳压器,单路输出、最大输出电流可达1A。器件内部集成过热关断与过流保护,适用于各类便携与固定电源系统,为单片机、传感器、无线模块等提供稳固的3.3V电源。
本器件采用SOT-223封装,占板面积小但热阻相对较高。工作在高负载或高差分电压时,器件会产生较大功耗(Pd = (Vin - Vout) × Iout),需通过合理的PCB铜箔散热、加大焊盘或外加散热片来降低结温,确保热关断不被误触发并提升长期可靠性。
AMS1117-3.3以其结构简单、外部元件少、噪声与纹波抑制良好而广泛应用于嵌入式和消费电子电源设计中。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
