AZ1117D-3.3TRE1 是一款由 DIODES(美台)生产的高性能线性稳压器(LDO),具有固定输出电压和出色的电源噪声抑制特性。该稳压器在各种电子设备和电路中表现出色,能够为微电子元件提供稳定的电源,保障其正常工作。
AZ1117D-3.3TRE1 的输入电压最大可达 15V,同时其输出电流能够稳定提供最高 1A 的电流负载。该稳压器的输出电压为固定值 3.3V,非常适合用于需要 3.3V 电源的应用场合,如微处理器、传感器和其他数字器件。
在 LDO 的性能指标中,PSRR(电源抑制比)是非常重要的一项。AZ1117D-3.3TRE1 的 PSRR 在 120Hz 的频率下达到 75dB,能够有效抑制输入电压波动带来的噪声,确保输出电压的稳定性。此外,其输出纹波抑制能力在使用环境中也能够降低电源噪声对负载的影响,从而提高电路的整体性能。
在负载电流达到 1A 时,AZ1117D-3.3TRE1 的最大压降为 1.25V。这意味着在输入电压为 3.3V+1.25V=4.55V 以上的条件下,稳压器能够提供足够的输出电流,有效降低能量损耗。同时,由于其低压差特性,该产品在使用时会提供更高的功率转换效率,有利于减少发热量,提高系统的可靠性。
AZ1117D-3.3TRE1 设计了多项保护功能以确保其安全运行。其中,热关断功能能够在稳压器温度超过设定阈值时自动停用,以防止设备损坏。这一特性尤其适用于温度背景较高的环境,额外提高了产品的耐用性和稳定性。
该稳压器的工作温度范围极广,从 -40°C 到 125°C(TJ),使其能够适应各种严苛的环境条件。因此,AZ1117D-3.3TRE1 特别适合用于工业自动化、汽车电子、电信设备等领域。
AZ1117D-3.3TRE1 采用 TO-252-2 封装,这一表面贴装型的设计可以节省电路板空间,同时便于高密度布局。其符合现代 SMT(表面贴装技术)要求,确保了良好的机械强度和导热性能。封装的设计考虑了散热问题,能够有效帮助器件在长时间负载运行过程中保持良好的工作温度。
由于其稳定性高、抗干扰能力强以及良好的保护特性,AZ1117D-3.3TRE1 在实际应用中得到广泛的推广,常见于以下场合:
AZ1117D-3.3TRE1 以其卓越的性能,可靠的安全特性和优秀的适应性,在电子元器件市场上占据了重要位置。无论是用于日常消费电子产品还是专业设备,该产品都能够为工程师提供一个高效、稳定、可靠的电源解决方案。正因如此,AZ1117D-3.3TRE1 成为众多设计项目中不可或缺的核心组件。
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.
