SGM2205-3.3XK3G/TR 是圣邦微(SGMICRO)推出的一款低静态电流、固定输出的线性稳压器,输出电压为 3.3V,单通道正输出,采用 SOT-89-3 封装。器件适用于对噪声与纹波有较高要求,同时对待机功耗敏感的便携与工业应用。
器件内置过流保护与短路限制,当输出发生过载或短路时会限制输出电流以保护器件;热关断机制在芯片温度过高时自动关闭输出并在温度降低后恢复,提高系统容错能力。
采用 SOT-89-3 小体积封装,适合空间受限的板级应用。线性稳压器的功耗等于 (Vin - Vout) * Iout,须注意散热:
总结:SGM2205-3.3XK3G/TR 在低静态电流、高 PSRR 与中等输出能力间取得平衡,适合对噪声、功耗和体积都有要求的 3.3V 供电场合。设计时应重视输入电压选择与散热布局,以保证长期可靠运行。

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.
