S-LR431AKLT1G 产品概述
一、产品简介
S-LR431AKLT1G 是乐山无线电（LRC）推出的一款高精度电压基准/可调并联稳压器，名义基准电压为 2.5V。器件在宽温度和电压范围内保持优秀的输出精度与稳定性，适用于精密参考源、基准电源、比较器参考以及带有少量负载的稳压场合。
二、主要性能特点
- 输出类型：可调（亦可作为固定 2.5V 精密基准使用）
- 名义输出电压：2.5V（典型范围 2.488V ~ 2.512V）
- 精度：±0.5%（初始精度）
- 输出电流：最高可达 100mA（请注意封装和散热限制）
- 最低阴极电流以保证调节：300 μA
- 工作电压范围：2.5V ~ 36V
- 工作温度范围：-40℃ ~ +125℃
- 温度系数：25 ppm/℃
- 封装：SOT-23E（小尺寸，便于表面贴装）
三、典型应用场景
- 精密电压基准与 ADC/DAC 参考源
- 可编程稳压与基准源（与外部分压电阻配合）
- 电池管理与便携式设备的低电流基准
- 基准驱动小功率放大器或比较器输入
四、设计与使用建议
- 保证至少 300 μA 的最低阴极电流以维持精度；在低负载工作时通过并联偏置电阻提供最小电流。
- 当需要较大负载电流（接近 100mA）时，关注 SOT-23E 的功耗与散热，必要时采用外部串联限流或功率分担器件。
- 输入工作电压应大于或等于基准电压（≥2.5V），并在高电压时做好去耦和过压保护。
- 温度漂移为 25 ppm/℃，在高精度系统中可通过外部温度补偿或软件校准进一步提高长期稳定性。
五、封装与采购提示
S-LR431AKLT1G 采用 SOT-23E 小封装，适合表面贴装加工。采购时请注意核对规格单、批次编码与温度等级，必要时参考厂商完整数据手册以获取引脚定义、最大额定值及典型电路图。
如果需要，我可以基于该器件给出参考电路、最小偏置计算或在不同负载/温度下的误差估算。
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.
