功能特点

可调输出电压

LM317LG-S08-R 具有可调输出电压功能,用户可以通过外部电阻网络来设置所需的输出电压,从1.25V到37V。这使得该器件在各种不同的应用场景中都能找到用武之地,无论是低压还是高压系统。

多重保护功能

该器件内置了多种保护功能,包括:

  • 短路保护: 当输出端短路时,器件会自动减少输出电流以防止损坏。
  • 热保护(TSD): 当器件温度超过安全阈值时,会自动降低输出电流或关闭输出,以防止过热导致的损坏。
  • 过流保护(OCP): 当输出电流超过设定值时,器件会限制或切断输出电流,以保护自身和下游电路。

这些保护功能确保了器件在各种异常情况下的可靠运行和长寿命。

低dropout电压

尽管LM317LG-S08-R是一款线性稳压器,但它仍然具有较低的dropout电压,这意味着在输入和输出电压差较小的情况下,器件仍能保持良好的稳压性能。

高精度和低噪声

LM317LG-S08-R 提供高精度的输出电压调节,并且具有较低的噪声特性,使其适用于对稳定性和精度要求较高的应用,如音频设备、医疗设备等。

应用场景

电源模块

由于其可调输出和多重保护功能,LM317LG-S08-R 常被用于各种电源模块中,为不同设备提供稳定的电源供应。

嵌入式系统

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
