XC6219B302MR-G 产品概述
一、产品简介
XC6219B302MR-G 是 TOREX（特瑞仕）推出的一款低压差线性稳压器（LDO），为固定输出型，输出电压为 3.0V，最高输出电流可达 240mA。器件采用 SOT23-5 小封装，适合对体积、效率和电源噪声有较高要求的便携及嵌入式应用场景。工作环境温度范围为 -40℃ 至 +85℃（Ta），适用于广泛的工业与消费电子产品。
二、主要性能特点
- 输出类型：固定（3.0V 正极输出，单通道）
- 最大工作电压（输入）：6V
- 最大输出电流：240mA
- 低压差特性：60mV @ 30mA（低压差，有利于电池供电系统）
- 低静态电流：Iq = 25μA（有利于延长待机寿命）
- 优异的电源纹波抑制：PSRR = 70dB @ 10kHz（对高频纹波有良好抑制能力）
- 工作温度范围：-40℃～+85℃（Ta）
- 封装：SOT23-5，体积小、适合密集 PCB 布局
三、优势与应用场景
- 节能待机：25μA 的静态电流非常适合电池供电设备与低功耗终端，可显著降低待机能耗。
- 低压差供电：60mV @ 30mA 的低压差特性允许在电池电压接近 3.0V 时仍能稳定输出，适合单节锂离子或两节镍氢电池等场合。
- 抗干扰能力强：70dB @ 10kHz 的 PSRR 在射频前端、无线模块及音频系统中可减少电源纹波对信号的影响。
- 小型化设计：SOT23-5 封装便于在空间受限的移动设备、可穿戴产品与物联网终端上使用。
典型应用包括：便携式终端、传感器结点、微控制器供电、无线通信模块、电池管理子系统、音频前端、工业控制等。
四、设计注意事项
- 输出/输入旁路：为保证稳压器稳定工作并获得最佳瞬态响应，建议在输入端与输出端各配置贴片电容（常用陶瓷电容值范围 1µF～10µF，根据应用电流与纹波要求调整）。
- 热设计：在高 Vin–Vout 差和大负载电流情况下，器件功耗增加（P = (Vin - Vout) × Iout），需关注 PCB 散热布局，增大铜箔面积以提升热性能。
- 布局建议：输入电容尽量靠近 VIN 引脚放置，输出电容靠近 VOUT，引脚与地之间的回流路径应尽量短且粗，减少噪声耦合。
- 启用/关断：若系统需要电源控制，请确认所使用封装版本是否带有使能（EN）功能，并按数据手册推荐方式接入控制信号。
五、小结
XC6219B302MR-G 是一款面向低功耗与高性能噪声控制应用的固定输出 LDO，兼具低压差、低静态电流和良好的 PSRR 性能。其 SOT23-5 小封装与 -40℃ 至 +85℃ 的工作温度范围，使其在便携式、无线及工业电子设计中具有良好的适用性。设计时注意输入/输出电容与散热布局，可充分发挥该器件在稳压与抗干扰方面的优势。若需详细引脚定义与典型电路参数，请参阅 TOREX 官方数据手册以获取完整规范与推荐设计。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
