ME6209A36PG 是南京微盟(MICRONE)系列的低压差线性稳压器(LDO),为固定输出型,输出电压为 3.6V,最大输出电流 250mA。器件支持最高工作电压 18V,静态电流(Iq)仅 3μA,适合对待机功耗要求严格的应用。典型封装为 SOT-89,单通道、正极输出,工作温度范围宽 (-45℃ ~ +150℃),适用于要求耐高温与低噪声的供电场合。
主要规格要点:
线性稳压器的功耗为 (Vin – Vout) × Iout。在极端工况下(例如 Vin = 18V,Vout = 3.6V,Iout = 250mA):
3.6W 的耗散对 SOT-89 小封装来说是较大的热负荷,若在此条件下长期工作,需要注意:
在实际设计中,建议根据预期最大工作电流和输入电压先行评估热余量,必要时采用散热片或改用更大封装/外置散热方案。
总结:ME6209A36PG 以其低静态电流、较低压降与宽温度范围,在低功耗和耐高温场合具有明显优势。但在高差压大电流工况下需重视热管理与电源架构设计,结合合适的输入/输出电容与 PCB 散热优化方能发挥最佳性能。有关更详细的电气特性与应用电路,请参考原厂完整规格书。

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.
