在现代电子设备设计中,稳压器作为重要的电源管理元件之一,扮演着至关重要的角色。AP7315-285FS4-7B 是一款由 DIODES(美台)公司生产的低压差线性稳压器,具备多种优越特性,广泛应用于消费电子、工业控制、通讯设备等领域,保证电路稳定工作。
输出配置与类型
这款稳压器的输出配置为“正”,采用固定输出方式。相比于可调型稳压器,固定输出型在设计及使用上更为简洁、稳定,用户只需关注其最小和最大输出电压范围即可。AP7315-285FS4-7B 的固定输出电压为2285V,非常适合需要稳定电源的小型电子产品,如传感器和微控制器供电。
输入电压范围
AP7315-285FS4-7B 的最大输入电压为5.25V,这使得它能够与多种电源兼容,尤其是在便携式设备中,广泛使用的锂离子电池(通常为3.7V到4.2V)都在此范围内。
电流输出与功率特性
该稳压器能够提供高达150mA的输出电流,对于绝大多数普通电子模块供电是足够的。其输出电压降最大值为0.29V(在150mA时),这表明该器件具有较小的压降,能够在保证性能的前提下提升能效,减少能量损耗。
静态电流
AP7315-285FS4-7B 在静态时仅需60µA(Iq),这一数值指示器件在无负载情况下的电流消耗极低,有助于延长电池供电的设备的使用寿命,同时对于电源管理、极大降低功耗具有积极影响。
电源抑制比 (PSRR)
该稳压器的PSRR达到了75dB(1kHz),展现出在处理输入电压波动(如噪声或干扰)时具备很强的抑制能力。这对于需要稳定电源的敏感电子产品而言,保证了信号完整性和系统可靠性。
AP7315-285FS4-7B 还内置了过流保护功能,这使得其在异常情况下(如短路或负载过重)能自动保护电路,避免损坏。这种保护机制为产品的长时间可靠运作提供了保障,使其成为各种应用场合的首选组件。
宽广的工作温度范围
该稳压器的工作温度范围为-40°C 到 85°C,使其能够在苛刻的环境条件下运行,因此在工业、汽车电子以及其他严苛应用场景中表现出色。
AP7315-285FS4-7B 采用表面贴装型封装(4-XDFN 裸露焊盘),尺寸小巧,有助于紧凑型电子设备的设计。同时,其封装形式也便于自动化生产装配,有效提升生产效率。
AP7315-285FS4-7B 作为低压差线性稳压器,适合为各类低功耗设备提供稳定电压,如:
综上所述,AP7315-285FS4-7B 以其优异的电压稳定性、低功耗设计及保护功能,无疑是在性能与可靠性之间取得了良好平衡的稳压器选择,适合现代电子设计中对稳定、可靠电源的高要求。
Request for quote
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.
