SGM2202-3.3AYN5G/TR 是圣邦微(SGMICRO)推出的一款固定输出线性稳压器,输出电压为 3.3V,最大输出电流 150mA。器件采用 SOT-23-5 小封装,具有非常低的静态电流(Iq = 6.5µA),并带有过热保护功能,适合对待机功耗敏感且空间受限的电子设备。典型电源纹波抑制比(PSRR)为 55dB(217Hz),在抑制低频干扰方面表现良好。
线性稳压器的耗散功率 Pd = (Vin - Vout) × Iout。在满载 150mA 且输入电压接近 6V 时,Pd ≈ (6V − 3.3V) × 0.15A ≈ 0.405W。若输入电压更高(例如 9V),Pd 会增加至 0.855W,易触发热保护并影响稳定工作。SOT-23-5 封装的散热能力有限,设计时应:

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.
