ME78L05PG 是南京微盟(MICRONE)推出的一款固定输出线性低压差稳压器(LDO),输出为正5.0V,单通道设计,最大输出电流100mA。器件适用于需要稳定5V供电且输入电压可达30V的场景,内置短路保护与过热保护,工作可靠,封装为SOT-89-3,便于中小功率模块化设计。
SOT-89-3 小型封装,适合空间受限的板级设计。三引脚布局利于散热和布线,标准封装有利于加工和焊接。具体引脚序号请参考器件数据手册。
SOT-89-3 封装具有限制的散热能力,工作时需关注功耗(Pd = (Vin - 5V) × Iout)。在高输入差与接近100mA负载工况下,应通过增加铜箔面积或散热片降低结温,避免触发热关断。
若系统输入电压波动较大、需更高电流或更低压差,可考虑低压差(LDO)或开关型稳压器作为替代;若对PSRR要求高且频段敏感,参考实际测试数据以确认器件性能满足需求。购买与技术细节请参照MICRONE官方数据手册和样片报价。

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.
