LM7806T 产品概述
一、产品概述
LM7806T 是华冠（HGSEMI）出品的固定输出线性稳压器，采用常见三引线 TO-220 塑料封装，适用于电视机、收录机、各类电子仪器及一般电源模块。器件输出为正极性，额定输出电压为 6V，最大输出电流可达 1.2A，结构简单、使用方便，便于与散热片配合以满足中等功率供电需求。
二、主要性能指标
- 输出电压：6V（固定）
- 输出电流：最大 1.2A
- 工作电压：最高可承受 35V 输入
- 电源纹波抑制比（PSRR）：59dB @ 120Hz
- 噪声：典型 45μV
- 工作温度范围：0℃ ~ +125℃
- 保护特性：短路保护、过流保护、热关断
- 输出通道：单通道
- 封装形式：TO-220（便于散热处理）
三、典型应用场景
适用于各类需要稳定 6V 电源的消费电子产品与仪器设备，如小型音频设备、控制电路板、传感器供电、电源模块等。对线路中纹波抑制和低输出噪声有一定要求的场合，LM7806T 可提供可靠的线性稳压性能。
四、封装与散热建议
TO-220 封装便于采用外加散热片或机箱底板散热。设计时应关注功率耗散：Pd ≈ (Vin - 6V) × Iout。当输入电压高且输出电流接近额定值时，器件会产生较大热量，需配合合适散热片或强制风冷以避免触发热关断。
五、使用注意与建议
- 为保证稳压器稳定工作，建议在输入端并联 0.33μF 陶瓷或高频电容，输出端并联 0.1μF 陶瓷及适当的电解电容（如 10μF）以提高瞬态响应与抑制振荡。
- 设计时应避免长期在高差压、高电流下工作，以减少热应力并延长寿命。
- 依靠内置保护电路可提升系统可靠性，但仍需在 PCB 布局和系统设计中做好散热与短路防护。
LM7806T 以其实用的固定输出和完善的保护功能，是中低功率稳压需求的可靠选择。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
