MD7333H 产品概述

一、产品简介

MD7333H 是明达微推出的一款高耐压、超低静态电流的固定输出线性稳压器(LDO),采用SOT-89封装,面向对功耗与可靠性有严格要求的便携与工业应用。该器件提供3.3V固定输出、最高输出电流250mA,并具备短路与过流保护,适合在宽温范围内长期稳定工作。

二、主要规格(关键参数)

  • 输出极性:正极
  • 最大工作电压:40V
  • 输出电压:3.3V(固定)
  • 最大输出电流:250mA
  • 压差(Dropout):60mV @ 10mA
  • 静态电流(Iq):2.2μA
  • 保护功能:短路保护、过流保护
  • 工作温度范围:-40℃ ~ +85℃(Ta)
  • 输出类型:固定输出,单通道
  • 封装:SOT-89

三、性能特点与优势

MD7333H 静态电流极低(2.2μA),非常适合电池供电与低功耗待机场景;在轻载条件下压差极小(10mA时仅60mV),有利于延长电池使用时间或在低压差场合提供稳定输出。器件内部集成短路与过流保护,提高系统的可靠性并简化外围保护设计。SOT-89小型封装兼顾功耗散热与PCB空间利用。

四、典型应用场景

  • 低功耗便携设备与可穿戴终端
  • 电池管理与电源模块(3.3V逻辑供电)
  • 工业控制与传感器节点
  • 家用电器与楼宇设备中对稳压与保护有要求的子系统

五、使用建议

  • 推荐在输入端与输出端分别并联合适的去耦电容以保证稳定性;具体电容类型与容量请依据应用的瞬态需求及器件手册选择。
  • 注意器件在高电压差与高功率散失情况下的热管理,SOT-89 封装需合理布线与散热铜箔以保证长期稳定工作。
  • 在设计保护与布局时考虑过流/短路触发条件及系统恢复策略,以避免误动作或循环重启对系统的影响。

六、封装与订购信息

MD7333H 提供标准 SOT-89 封装,适配常见SMT工艺。具体订购型号、引脚定义与包装信息请参见明达微产品手册或联系供应商获取最新版资料。

Sourcing availability signal

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
