XC6504A2519R-G 产品概述

一、概览

XC6504A2519R-G 为 TOREX(特瑞仕)推出的一款超低静态电流线性稳压器(LDO),固定输出 2.5V,面向电池供电和低功耗系统。器件工作电压最高可达 6V,输出电流可达 150mA,典型静态电流仅 600nA(0.6µA),非常适合长待机与窄电流感知场景。

二、主要性能参数

  • 输出极性:正极,固定输出 2.5V
  • 最大输入电压:6V
  • 输出电流:最大 150mA(建议在散热和压差允许范围内使用)
  • 压差:260mV @ 50mA(高电流时压差会增加,应留意)
  • 静态电流(Iq):600nA(典型值)
  • 工作温度范围:-40℃ ~ +85℃
  • 封装:USPN-4B02(小型封装)
  • 功能特性:外部使能(EN)、过流保护(OCP)、短路保护、输出放电功能

三、功能与保护

XC6504A2519R-G 集成使能控制,可通过 EN 引脚实现输出开/关,并在关断时通过输出放电功能快速释放输出电容上的残余电荷。内部具备过流与短路保护机制,提高系统可靠性;当输出被短路或过流时,器件会自动限制电流并在条件恢复后恢复正常工作。

四、典型应用场景

  • 电池供电的便携设备、穿戴式终端
  • 物联网节点、无线传感器(长待机/低平均功耗)
  • 低功耗微控制器、传感器电源隔离或基准电源
  • 需要快速断电输出释放的系统

五、设计与布局注意事项

  • 输入/输出旁路:建议在 VIN 处放置 0.1µF1µF 陶瓷电容,COUT 建议 1µF10µF X5R/X7R 类陶瓷,以保证稳态与瞬态响应。电容应尽量靠近引脚放置,走短而粗的走线。
  • 散热评估:最大功耗约为 (VIN - VOUT) × IOUT。例如 VIN=6V、VOUT=2.5V、IOUT=150mA 时器件功耗约 0.525W,需要通过 PCB 铜箔热扩散与良好散热设计降低结温,避免长期满载。
  • 压差与输出能力:标注的压差为 260mV@50mA,高电流工况下压差会上升,请根据系统最大 VIN 与所需 IOUT 留有足够裕量。
  • 使能逻辑:EN 为高电平使能,禁能时输出被放电到接近 0V,适合需要快速拉低输出的电源管理场景。

六、封装与可靠性

USPN-4B02 超小封装利于空间受限设计,但热阻较大,应通过底层或周围铜箔散热。器件通过常温范围以及汽车级以外的工业级温度范围测试,适用于 -40℃ ~ +85℃ 工况。

七、选型建议

在追求最长待机寿命与最低静态功耗的便携/传感场景下,XC6504A2519R-G 是优选;若系统经常工作在高电流(接近 150mA)或 VIN - VOUT 较大时,请务必做热仿真与实测,并考虑外部降压或并行散热方案以保证可靠性。

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
