XC6219B282MR 产品概述

XC6219B282MR 是友台半导体(UMW)推出的一款单路线性稳压器(LDO),面向低功耗便携与嵌入式电源管理应用。器件支持可调输出(1.8V~5.0V),最大输出电流可达300mA,封装为 SOT23-5,集成使能与过流保护功能,适合对噪声、功耗与尺寸有严格要求的系统。

一、主要特性

  • 输出类型:可调(1.8V ~ 5.0V)
  • 最大输入电压/工作电压:7V
  • 最大输出电流:300mA
  • 静态电流(Iq):典型 15µA(待具体数据表确认)
  • 电源纹波抑制比(PSRR):40dB @ 1kHz
  • 带使能(EN)控制端,可实现电源开关功能
  • 内置过流保护(OCP),提高系统可靠性
  • 输出极性:正极输出,单通道输出设计
  • 工作温度范围:-40℃ ~ +85℃
  • 封装:SOT23-5,便于小尺寸布局与批量生产

二、电气与功能描述

XC6219B282MR 为线性稳压器,内部集成误差放大器与功率管,通过外部分压电阻实现目标输出电压的精确设定。EN 引脚用于快速使能或禁用输出,便于系统省电管理;当载流超过限流阈值时,器件进入限流保护以防止过载或短路对电源及负载的损害。其较低的静态电流使得该器件适用于电池供电设备,PSRR 在音频或射频前端电源滤波中也表现良好。

三、典型应用场景

  • 电池供电的便携设备与穿戴式终端
  • 物联网(IoT)节点、传感器与低功耗 MCU 电源
  • 工业控制与测量仪器的局部稳压
  • 通信模块、模拟前端与基带电源管理
  • 需要可调电压输出和电源启停控制的子系统

四、设计与布局建议

  • 输入/输出端配合旁路电容:为保证稳压器稳定性与瞬态响应,应在靠近器件的输入和输出端放置合适的去耦电容(具体电容类型与数值请参照数据手册)。
  • EN 引脚接法:若需上电默认使能,可通过上拉;若需低电平使能或反向控制,请确认 EN 的逻辑电平要求。
  • PCB 布局:SOT23-5 封装散热能力有限,建议在器件下方与周边布置适当的铜箔散热区并通过过孔连接多层地/电源层以提高散热性能和降低寄生阻抗。
  • 过流与热保护:虽然器件具备过流保护,但在长期高电流工况下需关注热耗散与环境温度,必要时采用热降额设计。

五、选型与封装信息

  • 品牌:UMW(友台半导体)
  • 型号:XC6219B282MR
  • 封装:SOT23-5
  • 通道数:1(单输出)
  • 订货与替代:在选型时请确认目标应用所需的输出电压调节范围、启用逻辑及环境温度要求,并参考完整数据手册以获取更详细的参数、典型应用电路与可靠性信息。

XC6219B282MR 以其低静态电流、集成使能与保护功能以及小封装,适合在对功耗和空间有较高要求的系统中作为主/辅助稳压电源单元。具体电气特性(如 dropout、电压精度、EN 门限、保护阈值及电容兼容性)请以官方数据手册为准。

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
