MD7672B50SF4线性稳压器(LDO)产品概述

MD7672B50SF4是明达微推出的一款低压差可调线性稳压器(LDO),针对中低功耗、中等负载的稳压场景设计,兼具高可靠性与宽适应性,覆盖工业控制、便携式电子等多领域应用。

一、产品核心定位与基础规格

作为可调式LDO,MD7672B50SF4的核心基础规格明确:

  • 输入电压:额定6V(适配常见5~7V输入范围);
  • 输出特性:1.2V~5V宽范围可调(典型应用输出5V),最大输出电流2A;
  • 封装形式:ESOP-8贴片封装(尺寸紧凑,适配自动化贴装与紧凑PCB设计);
  • 工作温度:-40℃~+85℃(工业级宽温范围,满足户外、高低温环境需求)。

其核心身份是“低压差可调LDO”——相比传统线性稳压器,低压差特性(250mV@2A)大幅降低了输入输出压差要求,更适合输入电压接近目标输出的场景。

二、关键性能参数深度解析

MD7672B50SF4的性能参数针对性解决了稳压场景的核心痛点:

1. 低压差与大电流平衡

压差仅250mV(输出2A时),意味着当输入电压为5.25V时即可稳定输出5V(满足低输入压差场景);最大输出电流2A,可覆盖中等负载需求(如微处理器、传感器组、小型电机驱动等)。

2. 低纹波与低静态电流

  • 电源纹波抑制比(PSRR):70dB@1kHz(抑制高频电源纹波能力强,输出电压纯净,适合对噪声敏感的电路,如模拟信号处理、高精度传感器供电);
  • 静态电流(Iq):仅40μA(远低于传统LDO的mA级静态电流),电池供电场景下可显著延长续航(如便携式仪器、无线终端)。

3. 宽温与极性设计

  • 工作温度覆盖-40℃~+85℃,可适应工业现场的低温、高温环境(如户外监控、车载辅助系统);
  • 输出为正极性,适配绝大多数常规电子电路的供电需求(无需额外极性转换)。

三、全面保护功能配置

MD7672B50SF4内置多重保护机制,提升系统可靠性:

1. 过流与短路保护

  • 过流保护:输出电流超过阈值时自动限流,避免负载过载或器件损坏;
  • 短路保护:输出端短路时切断输出,待故障排除后自动恢复(防止短路故障扩散)。

2. 过热保护与使能控制

  • 过热保护:芯片结温过高时(如负载长时间过载)自动关断输出,温度下降后恢复,避免器件烧毁;
  • 使能功能:支持外部信号控制LDO开启/关闭,系统级节能管理(如休眠模式下关闭非必要供电)。

四、典型应用场景示例

结合性能参数,MD7672B50SF4的核心应用场景包括:

  1. 工业控制模块:为PLC、传感器节点、小型执行器供电(宽温适配工业环境,保护功能提升可靠性);
  2. 便携式电子设备:如手持测试仪、无线通信终端(低静态电流延长电池续航,可调输出适配多模块供电);
  3. 消费类电子:机顶盒、路由器、智能音箱的局部稳压(2A电流满足芯片组、WiFi模块供电,低纹波提升信号质量);
  4. 车载辅助系统:如车载摄像头、中控小模块(-40℃~+85℃宽温适配车载环境,保护功能避免故障)。

五、封装与可扩展性

采用ESOP-8贴片封装,尺寸小巧(约5mm×6mm),可直接兼容自动化贴装产线,适合高密度PCB设计;可调输出特性支持通过外部电阻调整电压(1.2V~5V连续可调),适配不同负载的电压需求,无需更换器件。

综上,MD7672B50SF4是一款高性价比、宽适应性的可调LDO,平衡了低压差、大电流、低功耗与宽温特性,内置多重保护,适合对可靠性与灵活性有要求的中低端稳压场景。

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
