LM317LZ 产品概述
LM317LZ是由意法半导体（STMicroelectronics）推出的一款高性能线性稳压器（LDO），广泛应用于提供稳定的直流输出电压。该器件以其优良的稳压特性和高效的电源管理能力，成为各类电子设备中不可或缺的关键元件。
基本特性
LM317LZ具有可调输出的特点，使其能够生成范围广泛的输出电压。其输出电压可调节至最低1.2V，最高可达37V，且适用于各种低功耗应用。此型号最低输入电压为1.25V，加上负载电压，最大允许的输入电压为40V，这使LM317LZ能够适应多种电源环境。
在最大输出电流为100mA的条件下，LM317LZ能够非常稳定地提供所需的电流，适合驱动小型负载。同时，其良好的电源抑制比（PSRR）在80dB至65dB的范围（在120Hz频率下）则有效地减少了电源波动对输出电压的影响，确保电路更稳定。
保护功能
LM317LZ还集成了多种保护功能，包括超温保护和短路保护，这为设计者提供了更高的安全性保障。超温保护功能在器件温度超过安全界限时自动停用，从而防止由于过热而造成的损害；短路保护确保了在发生短路情况时，稳压器可以自动工作，防止进一步的电路损坏。这样的设计不仅提升了设备的长期可靠性，同时也为方案的设计带来了更大的灵活性。
工作温度
LM317LZ的工作温度范围为0°C至125°C，使其能够在不同环境条件下稳定工作。这一特性使得LM317LZ非常适合于汽车、工业控制和消费电子等广泛应用领域，不论是室内还是室外环境均可可靠运行。
封装和安装
LM317LZ采用TO-92-3型封装，具有通孔安装方式。TO-92-3封装小巧的特点使其能够便捷地被集成到各种电路板设计中，节省空间并提升设计的整洁性。
应用场景
得益于其优异的性能和灵活的调节能力，LM317LZ可广泛应用于多个领域，包括：
- 消费电子：如便携式电子设备、玩具和小型家电，提供稳定的低压供电。
- 工业设备：用于各种传感器和控制电路，确保在恶劣环境下设备的可靠运行。
- 汽车电子：适合车辆供电系统中的低功耗设备，确保长时间稳定运行。
- 通信设备：用于基站和小型通信模块的供电，保持通信信号的稳定。
总结
LM317LZ是一款优良的线性稳压器，凭借其稳压能力、广泛的应用范围和出色的保护功能，已成为设计师和工程师在开发电源管理方案时的重要选择。无论是在经济性、可靠性或者灵活性方面，LM317LZ都表现出色，其小巧的封装和易于集成的特点，进一步推动了高效可靠电源设计的发展。选择LM317LZ就是选择了一个性能卓越、值得信赖的电源解决方案。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
