SPX2945M3-L-3-3/TR 是由 MAXLINEAR(迈凌)公司生产的一款线性稳压器(Linear Voltage Regulator),它属于MAXLINEAR的SPX2945系列。这个器件设计用于提供高效、可靠的电压稳定输出,特别适用于各种电子设备中对电源质量有较高要求的应用场景。
SPX2945M3-L-3-3/TR 提供固定3.3V的输出电压,最大输出电流达400mA,满足大多数中小功率电子设备的需求。其低电压降(最大0.7V @ 400mA)确保了在高负载条件下仍能保持稳定的输出。
该器件的静态电流(Iq)仅为300µA,这使得它非常适合用于低功耗应用,帮助延长电池寿命和减少总体能耗。
SPX2945M3-L-3-3/TR 具有优秀的PSRR(31dB @ 100kHz),这意味着它能够有效地抑制来自输入电源的噪声,从而提供更清洁和更稳定的输出电压。
器件内置了过流保护和超温保护功能,这些功能可以在异常情况下自动切断输出,以防止器件或系统受到损害,提高了整体的可靠性和安全性。
支持从-40°C到85°C的工作温度范围,使得该器件能够在各种环境条件下正常运行,适用于工业、汽车电子等对温度要求较高的应用场景。
采用SOT-223封装,这是一种常见且便于表面贴装的封装形式,简化了PCB设计和生产过程。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
