H7211-25M5R 产品概述

一、产品简介

H7211-25M5R 是上海矽朋(Siproin)推出的一款高性能固定输出线性稳压器,输入电压为 6V,固定输出 2.5V,最大输出电流 300mA。器件采用 SOT-23-5 小封装,集成使能(EN)控制与短路保护功能,适用于对噪声、纹波抑制和瞬态性能有较高要求的便携与工业电子应用。

二、主要性能特点

  • 输出类型:固定(2.5V)
  • 输出极性:正极
  • 最大输出电流:300mA
  • 压差(Dropout):180mV @ 150mA(在更高负载条件下需预留更大裕量)
  • 静态电流(Iq):30µA(典型)
  • 工作电压:6V(输入)
  • 工作温度范围:0°C ~ +85°C(Ta)
  • 使能功能:带使能(EN 引脚,用于开关控制,具体阈值请参考规格书)
  • 保护功能:短路保护与限流/热关断机制
  • 电源纹波抑制比(PSRR):75dB @ 1kHz
  • 输出噪声:50µVrms(典型)
  • 封装:SOT-23-5,小尺寸利于空间受限的应用

三、典型应用场景

  • 手持设备与便携终端的局部稳压电源
  • 传感器模组及数据采集前端的参考/供电源
  • 工业控制与通信终端的低噪声供电
  • 电池供电系统中作为子供电轨的低压差稳压器

四、封装与引脚说明

H7211-25M5R 采用 SOT-23-5 封装,体积小、易于表面贴装。器件提供输入(VIN)、输出(VOUT)、使能(EN)及接地(GND)等标准引脚。为确保稳定性和热性能,建议在 PCB 上优化散热走线与接地平面,并将输入/输出旁路电容尽量靠近相应引脚布局。

五、外部元件与布局建议

  • 输入端建议放置 1µF~10µF 的陶瓷旁路电容以抑制输入纹波与瞬态电流;若电源线较长,可加大电容或并联更大电容。
  • 输出端建议使用低 ESR 的陶瓷或钽电容(一般 1µF~10µF 范围)以保证稳压器稳定性与良好瞬态响应,具体容值与容器类型请按最终应用与参考电路调整。
  • 将输入/输出电容尽量靠近器件引脚放置,缩短走线并使用较宽的接地回流路径以降低噪声与热阻。
  • EN 引脚用于开关控制,若不使用请参照规格书建议接法(通常不能悬空)。

六、可靠性与使用注意事项

  • 该器件在 Ta = 0°C ~ +85°C 条件下工作,若系统工作环境超出该范围需评估热管理并确认器件寿命。
  • 规格中给出的压差为 150mA 工况下的典型值,满载 300mA 时压差会有所增加,设计时输入电压需预留足够裕量以保证输出稳压。
  • 虽然器件具有短路保护,但频繁或长时间的短路/过载会增加器件温升,应在 PCB 布局与散热设计上充分考虑。
  • 在高速或对噪声特别敏感的模拟电路周边使用时,注意良好接地与屏蔽设计以发挥其低噪声与高 PSRR 的优势。

七、包装与采购信息

  • 品牌:Siproin(上海矽朋)
  • 型号:H7211-25M5R
  • 封装:SOT-23-5
  • 建议与供应商确认最小起订量、包装形式(卷带/管装/散装)及最新的可靠性与符合性资料(如 RoHS 及品质等级)。

如需原理框图、典型应用电路或完整电气特性曲线(温度漂移、负载瞬态、启动/关闭时序、EN 阈值等),建议索取器件的正式数据手册以获取详细参数与推荐应用设计值。

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
