ME6239A50M3G 产品概述

一、产品简介

ME6239A50M3G 是南京微盟(MICRONE)推出的一款固定输出 5.0V 线性稳压器(LDO),单通道、正输出,封装为 SOT-23-3。器件设计面向低静态电流与中等负载能力的电源管理场景,集成短路保护,适合电池供电与工业级应用。

二、主要特性

  • 输出电压:固定 5.0V(正极输出)
  • 工作电压范围:最高可达 30V(注:设计时应考虑功耗)
  • 输出电流:最高 250mA
  • 静态电流(Iq):典型 2.5µA,适合低功耗系统
  • 压差(Dropout):380mV @ 100mA(随电流增加而上升)
  • 保护功能:短路保护
  • 工作温度范围:-40℃ ~ +150℃
  • 封装:SOT-23-3,单通道

三、典型电气与热设计考虑

线性稳压器的功耗主要由 P = (Vin − Vout) × Iout 决定。举例:若 Vin = 12V、Vout = 5V、Iout = 200mA,则耗散功率约为 1.4W;SOT-23-3 封装的散热能力有限,长时间大功率工作会触及结温限制或触发热保护。因此在实际设计中应:

  • 限制输入电压或负载电流以控制耗散功率;
  • 在高压差应用中考虑外部散热或改用大封装/开关稳压器;
  • 留意压差随电流增长而增加(100mA 时为 0.38V,250mA 时压差会更大)。

四、封装与引脚

器件采用 SOT-23-3 小型封装,利于空间受限的便携与嵌入式产品。具体引脚排列、引脚功能及外部电容要求(输出电容的类型与等效串联电阻 ESR 对稳定性的影响)请参阅厂方数据手册以获得精确连接与元件选型指导。

五、应用场景

  • 电池供电的便携式设备、传感器模块与物联网终端;
  • 工业控制、通信模块中的局部稳压电源;
  • 低静耗待机电路、RTC 或微控制器的 5V 供电来源。

六、 PCB 布局与使用建议

  • 在 VIN 端放置合适的去耦电容并靠近引脚,减小走线和寄生感抗;
  • 输出端使用厂方建议的稳定电容,保证环路稳定性;
  • VIN、VOUT 与 GND 的走线尽量短且粗,地线采用单点或大面积铜箔以利散热;
  • 若需长期高电流或大压差工作,评估热阻并考虑散热片或改用大封装方案。

七、小结

ME6239A50M3G 以其超低静态电流与集成短路保护,适合对待机功耗敏感且需要稳定 5V 输出的中低功耗应用。选用时应重点关注输入电压到输出电流所产生的功耗与热管理,按照数据手册推荐的外围电容与布局实践进行设计,可获得可靠的长期运行表现。若需完整电气参数、引脚定义与典型应用电路,请参考厂方详细资料。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
