LM317K-TN3-R 产品概述

一、产品简介

LM317K-TN3-R 是一种广泛应用的可调线性稳压器,属于 UTC(友顺)品牌旗下的高性能电源管理解决方案。采用 TO-252-2(DPAK)封装,使其易于集成于各种电路设计中。该产品具有高电压调整范围、较高的输出电流能力和优秀的电源噪声抑制性能,因此在电子设备的电源管理中扮演着重要角色。

二、主要特性

  1. 可调输出电压:LM317提供了 1.25V 至 37V 的可调输出电压范围,满足了不同应用对稳压输出的需求。用户可以通过外部电阻的配置轻松调整输出电压。

  2. 输出电流能力:本稳压器能够提供高达 1.5A 的稳定输出电流,适合大部分中低功率电子设备的供电需求。

  3. 温度补偿:内置的温度补偿机制能够有效确保在宽广的温度范围内,维持稳压输出,减少因温度波动带来的影响。

  4. 短路保护:LM317内置短路保护机制,能够在出现短路故障时自动限制输出电流,有效保护负载及自身的安全。

  5. 过热保护:具有过热保护功能,当温度超过安全范围时,将会自动降低输出,确保元件的寿命和安全性。

  6. 简易设计:其简单的外部电路设计要求,使其在设计过程中能有效降低设计复杂性,加快开发周期。

三、应用场景

LM317K-TN3-R 线性稳压器广泛应用于电子产品的电源管理领域,具体应用场景包括但不限于:

  • 开关电源:作为开关电源的后级稳压,使得输出电压平稳且具备较低的波纹。

  • 工业控制系统:在PLC、传感器等工业控制设备中提供稳定的工作电压。

  • 消费电子:可用于智能手机、平板电脑及其他便携式电子设备的电源接口,确保供电稳定。

  • DIY 项目:适合电子爱好者在各种自行设计和制作的电路中使用,提供可调电源输出。

  • LED 驱动:用于LED灯具的供电,确保LED的亮度一致性。

四、构建电路实例

LM317K-TN3-R 的典型应用电路非常简单,主要由 LM317 本体及两个外部电阻组成:R1 和 R2。通过调整 R2,可以方便地设置输出电压 Vout,从而使其适应不同的应用需求。在使用 LM317 之前需保证输入电压 Vin 高于输出电压(建议至少高出 3V),同时还需确保其输入和输出端的电容,以提高稳定性和减小噪声。

五、总结

LM317K-TN3-R 作为一种高性能可调线性稳压器,其优异的电源管理能力、良好的电路保护特性和简单的设计方法,使其在电子工程师的电源设计中成为一个不可或缺的组件。无论是在消费电子、工业自动化还是DIY电子项目中,LM317K-TN3-R 的可靠性和灵活性,都能满足用户对电源稳压的需求。随着现代电子技术的发展,其应用范围将持续拓宽,应用前景广阔。

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
