HT7550-1 产品概述

一、产品简介

HT7550-1 是 TECH PUBLIC(台舟电子)推出的一款高性能固定式线性稳压器,输出极性为正极,标准输出电压为 5V,输出通道数为 1。器件针对工业控制和家庭自动化等对稳定电源有较高可靠性的场景设计,封装可选 SOT89-3(本条目封装为 SOT-89-3)、SOT23-5、SOT23-3L,便于在空间受限的电路板上使用。

二、主要电气参数

  • 工作电压(典型):24V,最大工作输入电压可达 28V。
  • 输出电压:5V(固定类型),输出精度±2%。
  • 最大输出电流:150mA。
  • 压差(Dropout):160mV @ 10mA(低压差特性,利于在高电压差环境下减少功耗)。
  • 静态电流(Iq):1.5µA(超低工作电流,适合低待机功耗系统)。
  • 保护特性:具备过流保护功能,增强系统可靠性。
  • 工作温度范围:-25℃ ~ +70℃。

三、产品特性与亮点

  1. 超低静态电流:1.5µA 的待机电流显著降低系统静态功耗,适合对能耗敏感的长期运行设备。
  2. 低压差设计:在轻载条件下 160mV 的压差可带来更高的效率和更小的热耗散。
  3. 精度稳定:±2% 的输出精度保证下游电路的供电稳定性,减少校准和补偿工作。
  4. 可靠保护:内置过流保护机制,有效防止短路或突发负载造成器件损伤。

四、应用场景

适用于工业控制模块、传感器供电、家庭自动化网关与控制器、仪表设备等需要稳压 5V 电源且对功耗、可靠性有一定要求的场合。

五、使用与封装建议

  • 输入侧应加足够的去耦电容以抑制开关瞬态与导线感性,输出侧也建议放置电解或陶瓷电容(常见 1µF~10µF)以保证稳压器稳定工作。
  • 在高输入电压或接近最大输出电流工况下,注意器件的发热与散热设计,必要时在 PCB 布局上增加散热铜箔或外加散热片。
  • 封装选择上,SOT-89-3 提供更好的散热性能,适合较高功耗应用;SOT23 系列适用于空间受限且功耗较低的场景。

六、封装与品牌信息

品牌:TECH PUBLIC(台舟电子)。本产品常见封装为 SOT-89-3(也可选 SOT23-5、SOT23-3L),便于直接替换或进行模块化设计。

如需进一步的电气特性曲线、引脚定义、典型应用电路或可靠性测试数据,可提供具体的设计要求以便给出更详细的资料与布局建议。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
