基础参数

  • 压差: 1.3V @ 1A
    • 这表明在输出电流为 1A 时,输入与输出之间的电压差为 1.3V。
  • 商品分类: 线性稳压器(LDO)
    • LDO 是一种低压差的线性稳压器,适用于需要低噪声和高精度输出电压的应用。
  • 最大输入电压: 15V
    • 该器件可以承受的最大输入电压为 15V,确保在正常工作范围内不会因过高输入电压而损坏。
  • 特性:
    • 热保护(TSD): 当器件温度超过一定阈值时,会自动减少输出电流或关闭输出,以防止过热损坏。
    • 过流保护(OCP): 当输出电流超过设定值时,器件会自动限制或切断输出电流,以防止短路或过载情况下的损坏。
    • 电源纹波抑制比(PSRR): 75dB @ 120Hz
      • 高达 75dB 的 PSRR 表明该器件在 120Hz 频率下具有极好的电源纹波抑制能力,能够有效地过滤输入电源中的噪声和纹波。
  • 输出极性: 正极
    • 该器件提供正极输出,适用于大多数电子系统的正电源需求。
  • 输出电压: 5V
    • 固定输出电压为 5V,适用于各种需要稳定 5V 电源的应用,如微控制器、传感器和其他数字电路。
  • 输出电流: 1A
    • 最大连续输出电流为 1A,满足中小功率设备的电源需求。
  • 输出类型: 固定
    • 输出电压是固定的,不需要外部调整元件。
  • 输出通道数: 1
    • 该器件提供单个输出通道。

封装和品牌

  • 封装: SOT-89
    • 小型化的 SOT-89 封装使其适用于空间有限的应用场景,同时也提高了散热性能。
  • 品牌: 友顺(UTC)
    • 由知名电子元器件制造商友顺公司生产,保证了产品的质量和可靠性。

应用场景

LD1117AG-50-AB3-A-R 适用于各种需要稳定、低噪声和高精度电源的电子设备,例如:

  • 嵌入式系统: 微控制器、单片机和其他嵌入式系统常需要稳定的 5V 电源。
  • 传感器和测量设备: 高精度传感器和测量设备要求低噪声和稳定的电源供应。
  • 通信设备: 无线通信设备、模块等也需要高质量的电源供应。
  • 消费电子产品: 智能家居设备、可穿戴设备等消费电子产品中也广泛应用。

优势

  • 高稳定性: 固定输出电压和高 PSRR 保证了输出电压的稳定性。
  • 多重保护功能: 热保护和过流保护功能确保了器件在异常情况下的安全运行。
  • 小型化封装: SOT-89 封装使其适用于空间有限的应用场景。
  • 高效散热: 小型化封装同时也提高了散热性能,延长了器件的使用寿命。

使用注意事项

  • 输入电压限制: 确保输入电压不超过 15V,以避免损坏器件。
  • 输出电流限制: 不要超过最大输出电流 1A,以防止过载和热损坏。
  • 散热设计: 在设计中考虑良好的散热措施,以确保器件在高负载情况下的正常工作。

总之,LD1117AG-50-AB3-A-R 是一款高性能、可靠性强且功能齐全的线性稳压器,广泛适用于各种需要稳定 5V 电源的电子设备。其小型化封装、多重保护功能和高稳定性,使其成为许多设计工程师的首选。

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
