MD7680E50PA1 产品概述
一、产品简介
MD7680E50PA1 是明达微推出的一款高压差分线性稳压器（LDO），固定输出 5.0V，最大输出电流 150mA，适用于需要从高压母线得到稳定 5V 电源的场合。器件最大工作电压可达 60V，封装为小型 SOT-89-3L，兼顾高压耐受与低外形尺寸的应用需求。
二、主要特性
- 输出电压：5.0V（固定极性为正极）
- 输出电流：最高 150mA
- 工作电压：最高 60V
- 压差（Dropout）：1.8V @ 150mA
- 静态电流 Iq：仅 2.3µA，适合低功耗和待机场合
- PSRR：80dB @ 100Hz，具备优异的电源纹波抑制能力
- 完善保护功能：短路保护、过流保护、反向电流保护、热关断及使能控制
- 工作温度范围：-40°C ~ +85°C（Ta）
三、电气与热管理要点
MD7680E50PA1 在高压输入条件下能直接承受 60V，但作为线性稳压器，其功耗与输入输出压差和负载电流成正比：Pd = (Vin - 5V) × Iout。SOT-89-3L 封装的散热能力有限，建议在大压差或持续满载工作时采取降压前级、外置散热或减少负载电流，以防止热关断触发或超温失效。典型设计中若需长期 150mA 输出，务必评估结温并通过布局和散热措施控制器件功耗。
四、典型应用
适用于各类需要从高电压或未稳压电源生成 5V 的场景，包括但不限于：工业控制电源、通讯设备中间电源、传感器与数据采集终端、便携/备用电池供电场合以及要求低静态电流和高纹波抑制的精密模拟电路。
五、封装与PCB布局建议
SOT-89-3L 小型封装利于空间受限设计，但热阻相对较高。建议：
- 输出端和地端放置足够的旁路与散热铜箔；
- 输入端放置 1µF10µF 的低 ESR 陶瓷/钽电容做去耦，输出端建议使用 1µF10µF 低 ESR 电容以保证稳态稳定性（根据应用验证）；
- EN 管脚用于系统上电序列与节能控制。
六、设计注意事项
- 在设计时务必计算最坏情况下的功耗与结温，必要时采用降压转换器作为前级以减小 LDO 上的压差与热负荷；
- 充分利用器件的保护功能，但勿依赖于保护作为长期过载工作方案；
- 在高纹波或敏感模拟前端应用中，可利用其 80dB@100Hz 的高 PSRR 特性改善系统性能。
MD7680E50PA1 以其高压承受、低静态电流与优良的保护功能，为需要从高压母线稳定生成 5V 的中小功率设计提供了一种体积小、功能完备的解决方案。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
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.
