MD7602D33 是明达微推出的一款高耐压、低静耗的正极性线性稳压器(LDO),固定输出为 3.3V、最大输出电流 1A。器件采用 TO-252(DPAK)封装,适合对稳定电源、高抑制纹波与保护功能有要求的车载、通信、工业和消费电子电源模块。
MD7602D33 内置多重保护机制:在过流或短路情形下限制输出电流,避免负载或器件损坏;当结温超限时触发热关断以保护芯片并在温度下降后自动恢复。使能引脚可实现软启或外部断电控制,方便电源管理和系统级保护策略。
TO-252 封装具有良好散热能力,建议在 PCB 设计时在器件下方和铜箔上扩展散热区,并通过过孔与底层铜层联通以降低结温。高压差和大电流工作下需考虑功耗与结温,合理评估功耗(P = (Vin - 3.3V) × Iout)并采取散热措施。
MD7602D33 以其高耐压输入、低静耗、高 PSRR 和完善的保护特性,适合需要稳定 3.3V 电源且对可靠性、抗干扰有要求的多种应用场景。若需更详细的电气特性曲线、引脚定义和典型应用电路,请参考明达微官方数据手册。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
