HT7530-1 产品概述

一、产品简介

HT7530-1 是 HOLTEK(台湾合泰/盛群)提供的一款固定输出线性稳压器(LDO),输出电压固定为 3.0V,单通道、正极输出,采用紧凑的 SOT-89-3 封装。器件支持最高工作电压 30V、最大输出电流 100mA,适用于对噪声和纹波要求较高且输出电流不大的电源稳压场合。

二、主要特性

  • 固定输出:3.0V(正极输出)
  • 最大输入电压:30V
  • 最大输出电流:100mA(连续)
  • 低压差特性:典型压差 100mV @ 1mA(低负载时压差极小,重载下压差会随电流上升)
  • 单通道设计,SOT-89-3 小封装便于中小功率应用
  • 适用于消费类电子、传感器电源、MCU 从电源、模拟电路电源等

三、引脚与封装

  • 封装:SOT-89-3(小型三引脚表面贴装)
  • 常见引脚排列(建议以官方数据手册为准):
    • 引脚1:输入(VIN)
    • 引脚2:接地(GND)
    • 引脚3:输出(VOUT)
  • 安装时注意封装底部和 PCB 的热散设计,保证器件在允许的结温范围内工作。

四、典型电气参数摘要

  • 输出电压:3.0V(固定)
  • 输出极性:正
  • 输出通道数:1
  • 最大输出电流:100mA
  • 最大工作电压:30V
  • 压差:100mV @ 1mA(说明在轻载时具有很低的压差;在更高输出电流下压差会增加,应参考数据手册的典型曲线)

五、应用建议与布板要点

  • 输入端建议并联一只 0.1µF 陶瓷旁路电容靠近 VIN 引脚以滤除高频噪声;输出端建议使用 1µF–10µF 低 ESR 电容(具体电容值与 ESR 要求请参考官方数据手册),并靠近 VOUT 与 GND 引脚放置以保证稳压器稳定性。
  • 热耗计算:Pd = (VIN - VOUT) × IOUT。举例:若 VIN 为 12V、IOUT 为 100mA,则 Pd = (12 - 3)V × 0.1A = 0.9W。若 VIN 接近 30V,Pd 可达 2.7W,SOT-89-3 在高功耗下需良好铜箔散热或采用降压方案以避免过热。
  • 布局要点:输入输出走线短且粗,接地采用单点或固体铜平面;SOT-89 的底部焊盘尽量利用大面积地铜以增强散热能力。

六、典型应用场景

  • 便携式设备的局部稳压(当输入电压差不大或电流需求较小时)
  • MCU、传感器、模拟前端的低噪声电源
  • 工业控制与仪表(需承受较高输入电压但输出电流有限的场合)
  • 辅助电源或基准源(对稳定性和低压差有一定要求的应用)

七、选型与注意事项

  • 在高输入电压且负载电流接近 100mA 的场合,应重点评估功耗与结温;必要时采用降压预稳压(如开关降压)或增大铜箔散热面积。
  • 输出电流若长期超过 100mA 会导致器件过热或触发保护,请按数据手册限定值使用。
  • 具体的引脚排列、电气特性曲线、保护特性(如过流、过温)与外接电容要求,请以 HOLTEK 官方数据手册为准。

总结:HT7530-1 提供了体积小、输出稳定且适合中低电流应用的 3.0V 固定 LDO 解决方案。合理的输入电压范围选择与 PCB 热管理是保证可靠运行的关键。

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
