ME6211C28R5G 产品概述

一、产品简介

ME6211C28R5G 是南京微盟(MICRONE)推出的一款低功耗、高性能固定输出线性稳压器(LDO),输出电压为正极性 2.8V,集成使能控制与过流保护,适用于对噪声和纹波敏感的电源前端和便携式电子设备。器件采用超小封装 SOT-353,便于高密度 PCB 布局与空间受限的系统设计。

二、主要规格(概要)

  • 输出类型:固定(2.8V)
  • 工作电压(输入):6V
  • 最大输出电流:450mA
  • 静态电流(Iq):30µA(典型,低待机功耗)
  • 压差(Dropout):220mV @ 200mA
  • PSRR:70dB @ 1kHz(良好的电源纹波抑制能力)
  • 输出噪声:50µVrms
  • 特性:带使能(EN);过流保护(OCP)
  • 工作温度:-40℃ ~ +150℃(Ta)
  • 输出极性:正极
  • 输出通道数:1
  • 封装:SOT-353
  • 品牌:MICRONE(南京微盟)

三、关键特性与优势

  1. 低待机电流:30µA 的静态电流使该器件非常适合电池供电或对待机功耗敏感的应用,可延长设备续航。
  2. 低压差设计:在 200mA 负载下仅约 220mV 的压差,能在较低输入电压下为负载提供稳定的 2.8V 输出。
  3. 高输出能力:最高可驱动到 450mA,满足多数模拟前端、传感器及 MCU 外围供电需求。
  4. 优秀的抗干扰性能:70dB@1kHz 的 PSRR 以及 50µVrms 的低噪声输出,有助于降低电源对敏感模拟电路和射频前端的干扰影响。
  5. 保护与控制:内置使能脚便于系统电源管理与低功耗策略实现;过流保护增强系统安全性,防止短路或异常负载损伤。

四、典型应用场景

  • 便携式消费电子(传感器模组、手持设备、可穿戴)
  • 模拟前端和低噪声放大器供电
  • 通信设备的基带或射频前端辅助电源
  • 工业测控与仪器仪表中对稳定电压与低噪声有要求的电源部分

五、封装与系统集成建议

ME6211C28R5G 的 SOT-353 超小封装适合空间受限的应用。为保证稳定性与最好性能,建议按照器件数据手册配置合适的输入与输出旁路电容以抑制瞬态响应与保证环路稳定;在输入侧增加陶瓷电容可改善瞬态与抑制高频噪声;输出侧旁路电容对噪声和 PSRR 表现有直接影响,应参考厂方推荐值与 ESR 要求进行选型。

六、使用注意事项

  • 请参考官方数据手册中的推荐外部元件、PCB 布局与散热注意事项,SOT-353 封装受限的散热能力在大电流条件下需注意热管理。
  • 启用使能功能时,应保证使能脚电压与时序满足规范以避免启动异常。
  • 在高温环境(例如接近 +150℃)下工作时,应关注器件的功耗与热降额,避免长期超规格应力。

ME6211C28R5G 以其低功耗、低噪声与高 PSRR 的组合,适合对电源质量有较高要求且空间受限的现代电子设备,是实现 2.8V 稳定电源的理想选择。若需详细原理图参考、外部元件建议或完整电气特性参数,请参阅厂方完整数据手册或联系供应商获取支持。

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
