XC6219B252MR 产品概述

一、概述

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。

二、主要特性

  • 输出电压范围:1.8V ~ 5.0V(可调)
  • 最大输出电流:300mA
  • 电源纹波抑制比(PSRR):40dB @ 1kHz
  • 静态电流(Iq):15µA(典型)
  • 带使能(EN)功能,支持关断节能
  • 过流保护(OCP)与热关断保护,增强系统可靠性
  • 工作温度:-40℃ ~ +85℃
  • 输出极性:正极,单通道输出
  • 封装:SOT23-5(适合空间受限应用)
  • 品牌:UMW(友台半导体)

三、电气性能与典型应用

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。

四、封装与引脚功能(概述)

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。

五、布局与热设计要点

  • 输入侧靠近 VIN 引脚放置低等效串联电阻(ESR)陶瓷电容,减小输入纹波与瞬态压降。
  • 输出侧根据器件稳定性要求配置合适的输出电容和最低 ESR,推荐并置一只 1µF~10µF 的陶瓷电容作主滤波。
  • GND 平面应尽量完整,布线短且宽,降低热阻与叠加噪声。
  • 在高负载或高环境温度条件下,考虑扩大铜箔散热区以避免热关断引起的输出下降。

六、应用建议与选型注意

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。

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
