XC6219B252MR-G 产品概述

一、产品简介

XC6219B252MR-G 是 TOREX(特瑞仕)推出的一款固定输出线性稳压器(LDO),输出电压为 2.5V,最大输出电流 240mA。该器件采用 SOT-25 小型封装,面向对尺寸、低静态功耗和低压差有较高要求的便携及嵌入式应用。器件集成过流保护、短路保护、使能引脚与热关断功能,便于系统级安全设计与功耗控制。

二、主要规格

  • 输出类型:固定(2.5V)
  • 最大工作电压:6V
  • 最大输出电流:240mA
  • 电源纹波抑制比(PSRR):65dB @ 10kHz
  • 压差(典型):70mV @ 30mA
  • 静态电流(Iq):25µA
  • 特性:过流保护、短路保护、使能控制、热关断
  • 工作温度范围:-40℃ 至 +85℃(Ta)
  • 输出极性:正极
  • 输出通道:单路
  • 封装:SOT-25(SMD)
  • 品牌:TOREX(特瑞仕)

三、核心特点与优势

  • 低静态电流:25µA 的静态电流使其非常适合电池供电与低功耗待机场景,延长系统待机时间。
  • 低压差表现:在 30mA 负载时仅约 70mV 的压差,可在较低输入与输出差压下维持稳定输出,有利于提高电源效率与节省电池余量。
  • 良好纹波抑制:10kHz 时 PSRR 达 65dB,可有效抑制开关电源或外部噪声对敏感模拟或射频电路的影响。
  • 完善保护机制:内置过流与短路保护以及热关断,提高系统可靠性,避免故障时对器件和整机的损伤。
  • 使能控制:使能引脚支持外部控制电源开关,便于节能管理和电源域控制。

四、典型应用场景

  • 便携式设备与移动终端(传感器、手持设备)
  • 电池供电系统与电源后级稳压
  • 物联网与低功耗传感节点
  • 模拟前端、数据采集、模数转换器(提供清洁 2.5V 参考/供电)
  • 工业控制与通信模块的电源管理

五、设计与布局建议

  • 输入/输出电容:为保证稳压器稳定与瞬态响应,应按厂商推荐配置输入与输出去耦电容。通常优先采用低 ESR 陶瓷电容以获得最佳性能,请参考 XC6219B252MR-G 的详细资料与应用说明书来确定容值与布局要求。
  • 布局要点:输入与输出走线应尽量短且宽,输入电容靠近器件 VIN 引脚放置;良好接地平面有助于抑制噪声与提升散热性能。
  • 功率与散热:在高输出电流和高输入-输出压差条件下,器件功耗增加,应评估封装散热能力与 PCB 散热路径,必要时通过铜箔散热或减小电流/压差运行以避免热关断动作。
  • 使能控制:使能引脚在系统上电顺序与逻辑电平控制中可用于快速关闭输出以降低静态功耗,注意使能输入的电压阈值与滤波设计。

六、采购与替代

XC6219B252MR-G 以 SOT-25 小型封装提供,适合表面贴装生产。选型时除关注电气性能外,还应确认封装尺寸、引脚排列与PCB布局匹配。若需更高电流、不同输出电压或更低噪声性能,可参照 TOREX 产品线或其他厂商同类 LDO 进行对比选型。

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
