HT7550-3 产品概述
一、概述
HT7550-3是一款由台湾合泰（HOLTEK）公司生产的线性稳压器（LDO），专为提供稳定的5V输出电压而设计。该产品能够在高达30V的输入电压下运行，最大输出电流为150mA，适用于各种低功耗电子设备。
二、主要特点
固定输出电压：HT7550-3提供固定的5V输出电压，简化了设计复杂性，使其能够与众多需求端电压为5V的设备兼容。
高输入电压范围：支持高达30V的输入电压，为开发人员提供更大的设计灵活性，使得它能够用于多种不同的应用场景中。
输出电流能力：最大输出电流为150mA，适合驱动一些低功耗的传感器、微控制器、和小型数码电路。
低静态电流：在待机模式下，HT7550-3的静态电流较低，有助于提高整体能效，特别是在电池供电的应用中表现尤为突出。
紧凑的封装设计：采用SOT-89-3封装，使其在电路设计中占用更少的板面积，适合对空间有严格要求的应用。
过热与过载保护：HT7550-3集成了过热保护和过载保护功能，这些保护机制确保了在运行条件异常下设备的安全性和稳定性。
三、应用场景
HT7550-3适用于多种电子产品，包括但不限于：
- 便携式电池供电设备
- 消费类电子产品
- 小型便携式传感器
- 无线通信设备
- 工业控制器和仪器
四、技术规格
- 输入电压范围：4.5V - 30V
- 输出电压：5V ± 2%
- 输出电流：最大150mA
- 静态电流：通常为30μA
- 工作温度范围：-40°C 至 +85°C
- 封装形式：SOT-89-3
五、典型电路
在实际应用中，HT7550-3可以通过简单的外部电路配置进行使用。一般情况下，要求使用适当的输入电压源，并在输入端和输出端接入适当的电容，以确保稳定性。输入端可以接入一个大约1μF的陶瓷电容，输出端则可以接入一个0.1μF的陶瓷电容，这样可以消除高频噪声，并保证良好的瞬态响应。
六、设计注意事项
在设计使用HT7550-3的电路时，以下几个注意事项至关重要：
输入电容和输出电容的选择：为了保证稳压器的正常工作，输入和输出端的电容需要根据实际应用情况进行选择，确保电源信号的平稳和缓冲。
散热管理：虽然HT7550-3具有一定的自动保护功能，但在高负载条件下，仍然需要考虑散热设计，以避免过温导致的性能下降。
电源地设计：有效的电源地设计对于降低噪声和干扰非常重要。确保稳压器的地与其他信号地良好隔离，以提高整体电路的稳定性。
七、总结
HT7550-3是一款高性能、功能强大的固定输出线性稳压器，凭借其30V的高输入电压和150mA的输出电流，适用于多种现代电子应用。其低功耗、过载及过热保护特性使其成为设计师和工程师的理想选择。无论是在开发便携设备、工业控制或消费电子产品，HT7550-3都能提供可靠的电源解决方案。

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.
