LM317T(XBLW)线性稳压器产品概述

一、产品定位与核心身份

LM317T(XBLW)是芯伯乐(XBLW)推出的可调式线性稳压器,属于经典LM317系列的品牌化落地版本,采用TO-220通孔封装,主打中小功率可调稳压场景——兼顾性能稳定性、实用可靠性与成本优势,广泛适配工业、消费电子、车载等多领域的供电需求,是替代传统固定稳压管的灵活选择。

二、核心电气参数与性能表现

该器件的参数围绕“宽范围可调+实用性能”设计,关键指标的实际意义清晰:

  • 电压范围:输入最大40V(适配常见市电整流后的直流电压),输出通过外部电阻可调节至1.2V~37V(覆盖低压逻辑电平到接近输入电压的宽区间,无需额外多组稳压电路);
  • 电流能力:持续输出电流最大1.5A,满足小型电机、单片机系统、传感器等中小功率负载的供电需求;
  • 纹波抑制:120Hz(市电整流后典型纹波频率)下PSRR达75dB,能有效过滤电源中的低频纹波,输出电压纯净度高,避免干扰敏感电路;
  • 噪声水平:输出噪声仅0.003%Vout,适合音频设备、测试仪器等对信号质量敏感的场景;
  • 静态电流:工作时静态电流10mA,常规负载下不会额外增加系统功耗负担,待机时可通过使能功能进一步降低功耗。

三、多重保护特性(安全可靠性)

为适配复杂应用场景,LM317T(XBLW)内置4重保护机制,保障器件与负载安全:

  • 短路保护:输出端意外短路时,自动限制输出电流,避免自身过热烧毁;
  • 过热保护:结温超过阈值(典型150℃)时,自动降额输出,防止长时间高温损坏;
  • 过流保护:输出电流超过1.5A阈值时,内部限流电路启动,保护负载与器件;
  • 使能控制:支持外部使能信号(高电平有效),可通过单片机或逻辑电路控制输出开启/关闭,方便系统待机功耗管理(如车载设备熄火后关断非必要供电)。

四、封装与工作温度范围

  • TO-220封装:通孔插装形式,散热面积大,易焊接(手工/批量生产均适配),可搭配散热片进一步提升功率能力(如长期1.5A输出时加散热片更稳定);
  • 宽温工作:支持-20℃~+125℃工业级温度范围,能适应户外(如监控设备)、车载(车厢高温/低温)等极端环境,可靠性优于普通商用级器件。

五、典型应用场景

LM317T(XBLW)的参数与特性使其适配多种落地场景:

  • 工业控制:PLC模块、温度传感器供电,宽温与保护特性适配车间粉尘、温度波动环境;
  • 消费电子:小型充电器、智能台灯的可调稳压部分,满足不同设备的电压需求(如手机充电5V、小风扇12V);
  • 车载电子:车载显示屏、行车记录仪供电,宽温与过流保护适配车内-30℃~85℃的温度波动;
  • 测试仪器:示波器、信号发生器的辅助电源,低噪声与纹波抑制保证测试精度;
  • DIY电子:爱好者制作的可调电源模块,TO-220封装易操作,电阻调节灵活,适合实验台供电。

该器件凭借经典LM317的成熟架构+芯伯乐的可靠性优化,成为中小功率可调稳压的高性价比选择,尤其适合对宽温、保护特性有要求的应用场景。

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
