LM7824T（HGSEMI）产品概述
一、产品简介
LM7824T 是 HGSEMI（华冠）推出的一款单通道固定输出线性稳压器（LDO/78xx 家族风格），输出电压为 24V、最大输出电流 1.2A，输入端最大工作电压为 35V。器件采用 TO-220 封装，散热方便并带有短路保护与过热保护，适用于需稳定正极 24V 电源的工业与消费类电子设备。
二、关键性能
- 输出类型：固定（24V 正极输出）
- 输出电流：最大 1.2A
- 额定工作电压：35V（输入端最大）
- 电源纹波抑制比（PSRR）：50dB @ 120Hz（对交流纹波有约 316 倍的抑制）
- 输出噪声：约 160 μV（低噪声输出）
- 保护特性：短路保护、过热保护
- 工作温度范围：0℃ ~ +125℃（Ta）
- 封装：TO-220（引脚及散热片，金属背板通常与输出相连）
三、典型电路与外部元件建议
- 为保证稳定性与瞬态响应，常在输入端并联 0.33 μF 陶瓷电容，在输出端并联 0.1 μF（或 1 μF/10 μF）电解或薄膜电容。具体容值以实际电路与数据手册建议为准。
- 为防止输入断电或输出短路导致器件反向应力，常加输入到输出的保护二极管（如 1N400x）或肖特基二极管。
- TO-220 金属背板通常与输出电位相连，如需在散热片上绝缘安装，请使用绝缘垫或隔离螺柱，并注意降低热阻。
四、热设计与功耗计算
线性稳压器的功耗等于 (Vin - 24V) × Iout。举例：若 Vin = 35V、Iout = 1.2A，则耗散功率 P = (35 − 24) × 1.2 = 13.2W，显著发热，必须采取散热措施。若连续大电流工作，建议使用适配的散热片或考虑改用开关降压方案以降低耗散功率与系统温升。
五、应用场景与选型建议
适用于需要低噪声、良好纹波抑制且电流不超出 1.2A 的 24V 线性电源场合，例如模拟电路供电、测量仪表、低速电机驱动的控制逻辑电源等。若输入电压较高或输出电流长期接近额定值，优先考虑散热设计或切换至开关电源以提高效率。
如需进一步的电气特性曲线、典型应用图或封装引脚图，请参照 HGSEMI 的完整数据手册以获得制造商规定的精确参数与建议。

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.
