基本参数

  • 压差（Dropout Voltage）: 1.3V @ 1A
    • 表示在输出电流为 1A 时，输入电压与输出电压之间的差值。
  • 商品分类: 线性稳压器（LDO）
    • 属于线性调节器家族，通过连续调节内部电阻来实现稳定输出。
  • 最大输入电压: 18V
    • 指明了该稳压器可以承受的最大输入电压，超过此值可能导致器件损坏。
  • 特性: 过流保护（OCP）
    • 当输出电流超过设定值时，会自动切断或限制输出，以保护器件和下游电路。
  • 电源纹波抑制比（PSRR）: 60dB @ 120Hz
    • 描述了稳压器在特定频率下对输入电源噪声的抑制能力，高PSRR表示更好的噪声抑制性能。
  • 输出极性: 正极
    • 输出为正电压，适用于大多数电子设备的正电源需求。
  • 输出电压: 1.5V
    • 固定输出电压，适用于需要稳定1.5V电源的应用场景。
  • 输出电流: 1A
    • 最大连续输出电流，满足大多数中小功率设备的需求。
  • 输出类型: 固定
    • 输出电压固定为1.5V，无需外部调节。
  • 输出通道数: 1
    • 单通道输出，适用于单一电源需求的应用。

封装和品牌

  • 封装: SOT-223
    • 小型化封装，适合空间有限的 PCB 设计，提高了布局灵活性。
  • 品牌: 友台半导体（UMW）

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
