LR6375A33M是乐山无线电(LRC)推出的固定输出型线性稳压器(LDO),主打「低静态功耗、宽输入电压范围、高纹波抑制」三大核心优势,专为对电源稳定性、功耗控制及环境适应性要求严苛的场景设计。作为单通道正极输出LDO,其输出电压固定为3.3V,可直接为MCU、传感器、通信模块等低压负载供电,无需额外电压调节电路,简化系统设计。
具备70dB@1kHz的PSRR,可有效衰减输入电源的高频纹波(如开关电源输出纹波、电网干扰),为高精度传感器、低功耗MCU等对电源噪声敏感的负载提供纯净供电,避免纹波干扰信号采集或电路工作。
静态电流仅5μA,远低于同类产品平均水平(多数常规LDO静态电流≥20μA)。极低的静态功耗可显著降低系统待机能耗,适合电池供电的便携式设备(如手持测试仪)或长期待机的物联网终端(如环境监测节点),有效延长电池续航。
LR6375A33M采用SOT-23-3封装,尺寸仅约2.9mm×1.6mm×1.1mm,占用PCB面积极小,适合空间受限的紧凑型设计(如车载仪表盘、小型工业模块)。
引脚配置(标准SOT-23-3定义):
引脚布局简单,仅需少量滤波电容即可稳定工作,进一步简化系统设计与生产流程。
为提升可靠性与系统安全性,器件集成三大核心保护:
LR6375A33M的工作结温范围为-40℃~+125℃,覆盖工业级与部分车载级温度要求:
器件采用LRC成熟工艺制造,抗电磁干扰(EMI)能力强,可靠性符合工业级标准,可长期稳定运行。
结合性能特点,典型应用包括:
LR6375A33M凭借低功耗、宽电压、高可靠性等优势,成为工业、车载、物联网领域中小功率负载供电的理想选择,可有效简化设计、降低能耗并提升系统稳定性。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
