产品简介
MC79L05ACDR2G 是 ON Semiconductor(安森美)推出的一款线性稳压器(LDO),专为提供稳定的负电压输出而设计。该稳压器具有多项优异的性能参数,是不少电子设计中不可或缺的组件。其输出电压为固定的 -5V,输出电流可达到 100mA,适合用于对负电压有需求的各类电路。
基本参数
MC79L05ACDR2G 的基本参数如下:
产品特性
MC79L05ACDR2G 的一项重要特性是其固定负电压输出,这在许多应用场景中是非常关键的,比如运算放大器电源、模拟电路接口、以及音频信号处理等。它的设计允许在较大的输入电压范围内工作,而且其输入电压上限为 -30V,使其能够在多种复杂环境中稳定运行。
该稳压器的电压降表现良好,在输出40mA时的最大电压降为1.7V,这意味着它在提供稳定的负电压输出同时,其效率也保持在可接受的范围内。此外,它的PSRR高达49dB,这一参数表明MC79L05ACDR2G能有效抑制输入电压中的变化对输出电压的影响,从而确保输出电压的稳定性。
热设计与保护功能
在电子设计中,稳压器的温度控制至关重要。MC79L05ACDR2G 具有内置的超温保护功能,可以在过热的情况下自动关闭,从而保护电路不受损坏。此外,短路保护(SCP)特性保证了电路在短路情况下也不会发生破坏,提升了整体电路的可靠性。
应用场景
MC79L05ACDR2G 稳压器适合于多种应用,包括但不限于:
在这些应用中,MC79L05ACDR2G 提供的稳定的 -5V 输出对于确保设备正常运行和提高工作效率至关重要。
封装与安装
该稳压器采用受欢迎的8-SOIC封装,适合表面贴装技术(SMT)应用,这种 compact 封装形式不仅有助于提高整体设计的空间利用率,还有利于自动化生产流程。SOIC 封装的特性使得MC79L05ACDR2G 能够方便地集成到各种电路板设计中。
总结
MC79L05ACDR2G 是一款功能强大且稳定性极高的负电压线性稳压器,凭借其高PSRR、保护功能和优良的电压输出特性,成为电子设计领域不可或缺的组件之一。无论是在消费电子、工业控制还是通信设备中,这款稳压器都能很好地满足用户对稳定负电压输出的需求。由ON Semiconductor 制造,确保了产品的质量和可靠性。
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.
