XC6219B182MR-G 产品概述

一、简介

XC6219B182MR-G 是 TOREX(特瑞仕)推出的一款高性能固定输出线性稳压器(LDO),面向对噪声、功耗和尺寸有严格要求的嵌入式与电池供电设备。该器件在最高输入电压约 6V 的电源系统中,可提供稳定的正向 1.8V 输出,最大输出电流 240mA,封装为小型 SOT-23-5(有时标注为 SOT-25-5),适合空间受限的应用场合。

二、主要特性

  • 固定输出电压:1.8V(正极输出)
  • 最大输出电流:240mA
  • 工作电源:适用于最高约 6V 的输入电压系统
  • 低静态电流:典型 55µA(Iq),有利于待机节能
  • 压降(Dropout):典型 400mV @ 100mA
  • 电源纹波抑制比(PSRR):约 65dB @ 10kHz,有利于抑制外部噪声
  • 带使能(EN)功能,便于电源管理与电路上电控制
  • 保护功能:过流保护(OCP)与过温保护(OTP)
  • 工作温度范围:-40°C ~ +85°C(Ta)

三、电气性能要点

XC6219B182MR-G 在中等负载下表现出较低的压降和良好的低频/中频噪声抑制能力,65dB(10kHz)PSRR 使其在模拟前端、电源敏感模块供电时能有效降低纹波干扰。400mV 的压降在 100mA 负载下足以支持多数数字芯片及传感器,静态电流 55µA 则对延长电池寿命有明显帮助。需注意,压降会随输出电流上升而增加,设计时应预留裕量。

四、封装与引脚(概要)

  • 封装:SOT-23-5(SOT-25-5 标注兼容)
  • 小封装利于 PCB 面积节省,但热量集中,布局时需考虑散热路径(接地大銅箔、合理走线)。
    (具体引脚定义请参考厂商数据手册以获取 VIN、VOUT、GND、EN 等精确引脚排列与功能。)

五、典型应用场景

  • 便携式设备与电池供电终端(低功耗待机)
  • MCU、传感器、通信模块的 1.8V 电源轨
  • 模拟前端、参考电源以及对噪声敏感的子系统供电
  • 工业控制、消费电子、物联网终端等要求稳压与保护的场合

六、应用建议与注意事项

  • 输入端与输出端应靠近器件引脚放置去耦电容,建议使用低 ESR 的陶瓷电容以确保稳定性与瞬态响应(具体容量与 ESR 范围请依数据手册推荐值选择)。
  • 布局时保证 VIN、VOUT 与 GND 的短路径,增大接地铜箔面积以提升散热性能与降低寄生阻抗。
  • 在高负载或散热受限环境中,注意器件功耗((VIN−VOUT)×IOUT)对结温的影响,必要时采用热扩散或改用更大封装/散热措施。
  • 使能脚(EN)可用于电源序列控制,EN 为高电平使能;具体阈值参见数据手册。

七、可靠性与保护

器件内置过流与过热保护机制,能在异常工况下限制电流并在温度升高时自动关断以保护芯片与系统负载,提高系统可靠性。长期工作环境建议在厂商规定的温度范围内,并遵循焊接与存储说明。

总结:XC6219B182MR-G 以其低静态电流、良好 PSRR 与紧凑封装,适合对功耗、噪声和空间有严格要求的 1.8V 供电场景。欲获取完整电气参数、引脚排列与典型应用电路,请参阅 TOREX 官方数据手册。

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
