ME6119C36M5G 产品概述

一、产品简介

ME6119C36M5G 是南京微盟(MICRONE)面向中低功耗、电源管理场景推出的一款固定输出线性稳压器(LDO)。该器件输出电压为 3.6V,输出电流可达 400mA,静态电流仅 60µA,适合对静态功耗敏感且需稳定 3.6V 电源的应用。器件内置多重保护功能(短路保护、过流保护、过热保护/热关断),并带有使能(EN)控制脚,封装为常用的 SOT-23-5,便于 PCB 集成与小尺寸系统设计。

二、主要规格与特性

  • 输出类型:固定(3.6V)
  • 最大输入电压(允许工作电压):18V
  • 最大输出电流:400mA
  • 静态电流(Iq):约 60µA(典型值)
  • 输出通道数:1(单输出)
  • 输出极性:正极输出
  • 工作温度范围:-40℃ ~ +125℃(Ta)
  • 封装:SOT-23-5
  • 保护功能:短路保护、过流保护、过热保护 / 热关断
  • 控制功能:带使能(EN)脚,支持外部开/关控制

这些特性使 ME6119C36M5G 在待机功耗、热管理及系统安全方面具备良好表现,适用于需稳定供电并具备基本保护功能的场景。

三、封装与引脚(概述)

ME6119C36M5G 采用 SOT-23-5 小封装,典型的引脚功能包括:

  • IN(输入):连接系统电源输入。
  • OUT(输出):稳压后的 3.6V 输出。
  • GND(接地):器件地。
  • EN(使能):用于软关断或唤醒器件(具体使能电平请参照厂商数据手册)。
  • 备用/其他功能脚(视具体引脚排列可能为 NC 或内部检测脚)。

注意:不同生产批次或型号的引脚排列可能存在差异,正式设计时请以厂商原始数据手册的引脚图为准。

四、应用与典型场景

  • 低功耗便携设备:对静态电流要求严格的电池供电系统(传感器节点、可穿戴设备)。
  • 工业与通信终端:如工控模块、数据采集单元中需要稳定 3.6V 电源的子系统。
  • 消费电子:充电器、便携外设、显示驱动等需要固定 3.6V 的模块。
  • IoT / 智能终端:MCU、射频模块、传感器前端等对供电稳定性与安全性有要求的场景。

五、设计注意事项与建议

  • 输入-输出差压与功耗:线性稳压器的功耗等于 (Vin - Vout) × Iout。若输入接近器件允许的上限(例如 18V)并在 400mA 负载下工作,功耗与热量会显著增加,应评估 PCB 散热能力并避免长时间在高差压、高电流下工作。
  • 散热与热关断:SOT-23-5 封装的散热能力有限。建议尽量减小 Vin - Vout 差值、增加 PCB 铜箔散热面积或使用热沉/散热铺铜来降低结温,防止热关断触发。
  • 输入/输出电容:为保证稳定性与瞬态响应,通常在输入端与输出端使用旁路/稳定电容(如 1µF–10µF 常见值,优先选择低 ESR 陶瓷电容)。具体电容值与 ESR 要求请参照器件数据手册。
  • 使能控制(EN):利用 EN 脚实现电源管理与省电功能。设计时应注意 EN 的有效电平、上电时序及 EN 与输入电压的关系,避免在非允许的状态下误触发。
  • 启动与瞬态:在大电流切换或负载突变时,输出瞬态会受到输入电容、输出电容和回路带宽影响。必要时可增加输出旁路电容或优化电容布局以改善瞬态性能。

六、可靠性与保护特性

ME6119C36M5G 内置短路保护、过流保护和热关断机制,能在异常工况下保护器件和负载。但这些保护并不能替代系统级的设计保护措施。建议在系统设计中结合熔断、限流电阻、合适的滤波与保护元件(如 TVS)来提高整体可靠性。

七、选型建议与补充说明

在选用 ME6119C36M5G 时,应综合考虑输入电压范围、负载电流、热管理与封装限制。如果系统常态下 Vin 与 Vout 差值较大且负载电流高,建议评估开关稳压器或采用多级电源方案以降低功耗与发热。最终设计前请以 MICRONE 官方数据手册为准,并参考典型应用电路与推荐布局以确保性能与可靠性。

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.
