TLV1117LV33DCYR 是 JSMSEMI(杰盛微)出品的一款固定输出线性稳压器,输出固定为 3.3V,最大输出电流 1A。器件采用 SOT-223 封装,内置过流保护与过热关断功能,工作结温范围为 -40℃ 至 +125℃,适用于对噪声和电源纹波有较高要求的单通道电源设计。描述信息已校验通过,可直接用于工程选型参考。
SOT-223 封装体积小,易于手工焊接与波峰焊,但散热能力有限。推荐做法:
总结:TLV1117LV33DCYR 以其低噪声、高 PSRR、完整的保护机制和宽工作温度,适合在空间受限且对供电质量有要求的 3.3V 应用中使用,但在 12V→3.3V、满载条件下必须重点考虑热耗散与散热设计。

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.
