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。
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。
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
