78M09 是一款由 SHIKUES (时科) 制造的线性稳压器(LDO),属于固定输出电压类型。该器件以其高性能、稳定性和广泛的应用场景而受到广泛欢迎。以下是对 78M09 的详细介绍。
78M09 具有优秀的电源纹波抑制比(PSRR),达到了 71dB @ 120Hz。这意味着它能够有效地过滤输入电源中的噪声和纹波,为下游电路提供清洁且稳定的电源。
该器件支持从 -40℃ 到 +125℃ 的广泛工作温度范围,使其适用于各种工业、汽车和消费电子应用场景。
在无负载状态下,78M09 的待机电流仅为 6mA,这对于低功耗设计尤其重要,可以显著减少系统的整体能耗。
最大输入电压可达 35V,这使得 78M09 能够处理来自不同类型电源的输入信号,并提供稳定的输出。
能够提供高达 500mA 的连续输出电流,满足中小功率电子设备的需求。
在工业控制系统中,78M09 可以作为稳定电源模块,为控制器、传感器和执行器提供可靠的电源。
由于其宽工作温度范围和高稳定性,78M09 非常适合用于汽车电子设备,如导航系统、娱乐系统等。
在消费电子产品中,如智能家居设备、可穿戴设备等,78M09 可以提供稳定且低噪声的电源,确保设备运行稳定。
在医疗领域,稳定且可靠的电源至关重要。78M09 的高PSRR和低待机电流使其成为医疗设备中的理想选择。
由于 TO-252 封装形式,需要确保良好的热接触以避免过热。建议使用散热片或其他散热措施来提高器件的可靠性。
为了进一步提高稳定性,建议在输入端添加适当的滤波电容和电感,以减少输入纹波对输出的影响。
在设计时应考虑添加输出保护措施,如短路保护、过流保护等,以防止意外情况下对器件造成损害。
SHIKUES 的 78M09 是一款功能强大、性能优异的线性稳压器,广泛应用于各类电子设备中。其高稳定性、宽工作温度范围和低待机电流使其成为许多设计工程师的首选。通过合理的设计和使用,这款器件可以为您的系统提供可靠且高效的电源解决方案。

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.
