XC6219B252MR 是一款面向便携与低功耗系统的线性稳压器,采用 SOT23-5 小封装,单路输出设计,支持可调输出(1.8V ~ 5.0V)并能提供最高 300mA 的负载电流。器件具备使能管脚和过流保护,静态电流仅 15µA,适合对静态功耗敏感的电池供电设备。
XC6219B252MR 在中等频段具有良好的噪声与抑制性能(PSRR 40dB@1kHz),适合为模拟电路、传感器前端、MCU、蓝牙/无线模块及低功耗外设提供稳压电源。低静态电流使其非常适合电池供电或待机时间要求高的便携设备。300mA 的输出能力覆盖大多数低功耗数字与模拟负载。
SOT23-5 小封装便于批量贴装与空间优化。常见引脚包括输入(VIN)、输出(VOUT)、地(GND)、使能(EN)和调节/参考(ADJ/FB)。在设计时注意输入/输出电容选择与布局以保证稳定性与瞬态响应。
选择 XC6219B252MR 时,应确认系统所需的输出电压范围与瞬态电流峰值是否在器件能力内。如果系统对低频抑制或更大电流有更高要求,可考虑更高 PSRR 或更大电流等级的线性稳压器或开启小型开关稳压+LDO 组合方案。对于电磁兼容与噪声敏感应用,配合适当的输入滤波与接地设计能显著提升整体表现。
总体而言,XC6219B252MR 以其低静态功耗、紧凑封装和实用的保护功能,适合智能穿戴、物联网终端、传感器节点等需兼顾功耗与体积的应用场景。

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.
