  1. 输出电流和电压:

    • 本设备的输出电流可达10mA,能够为小型负载提供充足的电力支持。
    • 输入电压可承受的最大值为450V,而输出电压范围在1.2V至438V之间,输出电压可调,有助于满足不同电路对电压的具体需求。
  2. 保护功能:

    • LR8N8-G 集成了过流和超温保护功能,确保在意外情况下仍能保持设备的安全性和稳定性。
    • 这些保护机制可以防止因电流过载或温度异常升高而导致的损坏,从而提高了整体系统的可靠性。
  3. 电源抑制比(PSRR):

    • 本稳压器在120Hz时的PSRR达到60dB,说明其在抑制输入电压波动方面表现出色。这一特性使它特别适合那些对电源噪声敏感的电子应用,能够提供更清晰的信号和更稳定的电压输出。
  4. 工作温度范围:

    • LR8N8-G 的工作温度范围为-40°C至85°C,适用于各种环境条件,从极冷到相对高温的应用场合,依然能够保持优良的性能。
  5. 封装类型:

    • 采用TO-243AA(SOT-89)封装,LR8N8-G 具备极小的占板空间,因此在设计密集型的电路时,可以有效节省空间,方便集成在各种设备内。

应用领域

LR8N8-G 的特性使其适用于多个行业和领域,包括但不限于:

  • 消费电子: 在手机、平板电脑和智能家居设备中,提供稳定的电源支持,确保设备的正常运行。
  • 工业控制: 在工控系统中,LR8N8-G 可以作为传感器和执行器的电源,以确保系统的稳定性和高效运行。
  • 通信设备: 在电话和无线通信设备中,稳定的电压输出是至关重要的,LR8N8-G 可以有效提高信号传输的质量。
  • 医疗设备: 在需要高可靠性和稳定电源的医疗仪器中,LR8N8-G 的多个保护功能可帮助提升设备的安全性。

安装与设计考量

LR8N8-G 的表面贴装型设计(SMD)使其在PCB设计中具有极大的灵活性和对应的空间优势。设计师在选择合适的稳压器时需注意以下几点:

  • 散热设计: 尽管 LR8N8-G 提供了超温保护,但优化的散热设计依然是确保设备长时间稳定工作的必要条件。有效的散热能够帮助延长组件的使用寿命。
  • 电源布局: 在电路板布局中,电源走线应尽量短且粗,减少电阻和电感,提高稳压器的响应速度和稳定性。
  • 旁路电容: 在稳压器的输入和输出端放置适当的旁路电容,可以进一步提升其性能,减少高频噪声对信号的干扰。

结论

LR8N8-G 是一款高效、稳定且功能全面的线性稳压器,适用于多种电子产品。其强大的输出能力、优秀的保护特性以及宽广的工作温度范围,使其在市场上极具竞争力。选择 LR8N8-G,不仅能够确保电源的稳定性,还能够提升整体系统的可靠性和性能。

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
