XC6221A282MR-G 线性稳压器产品概述

XC6221A282MR-G是日本特瑞仕(TOREX)推出的固定输出型低压差线性稳压器(LDO),专为低功耗、小型化电子设备设计,具备高可靠性与宽环境适应性,是便携终端、IoT节点等场景的理想电源方案。

一、产品核心属性与定位

作为特瑞仕XC6221系列的成员,XC6221A282MR-G的核心定位是小封装、低功耗、高稳定的单路固定输出LDO,基础属性明确:

  • 品牌:TOREX(特瑞仕)
  • 类型:线性稳压器(LDO)
  • 输出特性:固定2.8V正极输出,单通道
  • 最大输出能力:200mA(连续负载)
  • 封装:SOT-25-5(超小型表面贴装封装,5引脚)

二、关键性能参数与实际价值

该产品的性能参数针对性强,精准匹配低功耗场景需求,核心参数及实际意义如下:

1. 电压与负载能力

  • 工作电压:支持最高6V输入(需结合压差考虑最低输入电压);
  • 输出电压:固定2.8V(无外接电阻调整需求,精度符合工业级要求);
  • 压差特性:100mA负载下仅170mV(低压差核心优势)—— 例如3.7V锂电池电压衰减至3V时,仍能稳定输出2.8V,比普通LDO(压差≥500mV)更适配电池供电场景;
  • 输出电流:200mA连续负载(可满足多数小型传感器、MCU的供电需求)。

2. 纹波抑制与低功耗

  • PSRR(电源纹波抑制比):1kHz时达70dB—— 有效过滤输入电源的高频纹波(如开关电源噪声),输出电压纯净度高,适合对噪声敏感的模拟电路(如传感器信号调理);
  • 静态电流(Iq):仅25μA(典型值)—— 待机功耗极低,是智能手环、蓝牙耳机等便携设备延长续航的关键(设备待机时稳压器自身功耗可忽略)。

3. 保护与控制功能

  • 内置保护:过流保护(OCP)、短路保护(SCP)—— 负载异常时自动切断输出,避免损坏稳压器及后端电路;
  • 使能控制(EN):支持外部引脚控制开启/关闭,可通过MCU进一步降低系统待机功耗。

4. 环境适应性

  • 工作温度:-40℃~+85℃(工业级宽温)—— 可适应户外、车载等 harsh 场景,无需额外散热设计。

三、封装与应用适配性

XC6221A282MR-G采用SOT-25-5超小型封装,尺寸约2.9×2.8×1.1mm,具有以下优势:

  • 节省PCB空间:适配智能穿戴、IoT传感器节点等小型化设备;
  • 贴装便捷:符合主流SMT产线要求,支持批量自动化生产;
  • 外围极简:仅需输入/输出滤波电容(无需电阻调整),5引脚包含VIN(输入)、VOUT(输出)、EN(使能)、GND(接地)及内部反馈引脚。

四、典型应用场景

结合性能参数,XC6221A282MR-G的核心应用场景包括:

  1. 便携电子设备:智能手环、蓝牙耳机、便携式医疗设备(如血糖监测仪);
  2. IoT传感器节点:环境监测(温湿度、光照)、工业物联网(低功耗传感器);
  3. 小型MCU供电:低功耗MCU(如STM32L系列)的核心供电;
  4. 电池供电系统:3.7V锂电池(或两节AA电池)的稳压输出(压差小,适配电池电压衰减)。

五、产品优势总结

XC6221A282MR-G的核心竞争力体现在:

  • 低功耗:25μA静态电流,待机功耗可忽略;
  • 高稳定:70dB PSRR抑制纹波,固定输出精度高;
  • 小尺寸:SOT-25封装适配小型化设计;
  • 高可靠:多重保护+宽温范围,适合 harsh 环境;
  • 易使用:无需外围电阻调整,仅需滤波电容即可工作。

综上,XC6221A282MR-G是一款针对性强、性价比高的线性稳压器,能有效解决低功耗设备的电源稳压需求,是便携终端、IoT领域的优选方案。

Sourcing availability signal

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
