HT7533 产品概述

一、产品简介

HT7533 是 GOODWORK(固得沃克)推出的一款单通道、固定输出的低压差线性稳压器(LDO),输出电压为 3.3V,最大输出电流为 100mA。器件采用 SOT-23 小封装,工作温度范围为 -40℃ 至 +85℃(Ta)。本器件以超低静态电流与极小压差为显著特点,适合电源空间受限且对待机功耗敏感的系统。

关键参数一览

  • 输出类型:固定(3.3V)
  • 最大输出电流:100mA
  • 压降(典型):25mV @ 1mA
  • 静态电流(Iq):1.5µA
  • 工作温度:-40℃ ~ +85℃(Ta)
  • 输出极性:正极
  • 输出通道数:1
  • 封装:SOT-23
  • 品牌:GOODWORK(固得沃克)

二、主要特性与优势

  • 超低静态电流:1.5µA 的待机电流非常适合电池供电或待机时间要求高的便携设备,可显著延长电池寿命。
  • 极小压差:在轻载条件(1mA)时典型压差仅为 25mV,能在输入电压与输出电压差较小时仍维持稳压,利于降低系统功耗和节省电池电压裕量。
  • 单通道固定输出:内置 3.3V 基准,免去外部设定电阻,简化电源设计。
  • 紧凑封装:SOT-23 封装占板面积小,适合空间受限的消费类与工业电子产品。

三、典型应用场景

  • 物联网节点、传感器模组和无线射频前端(对低静态电流与稳定 3.3V 电源有需求)
  • 可穿戴设备与健康监测设备(长待机、低功耗关键)
  • 便携式测量仪器与消费电子(需要小体积电源解决方案)
  • MCU、传感器、低功耗射频芯片的局部稳压电源

四、设计与布局建议

  • 输入/输出去耦:为确保稳压器环路稳定并抑制瞬态响应,建议在输入端和输出端分别放置陶瓷去耦电容。常见做法是输入端放置 0.1µF~1µF,输出端优选 1µF 或更大(低 ESR)。电容器应尽可能靠近器件引脚布局以减小寄生电感与电阻。
  • 板级走线:建议采用较短且宽的电源走线,输出回路尽量靠近负载,地线采用局部地平面或短回路以降低噪声耦合。
  • 负载和瞬态:尽管 HT7533 在轻载时压差极低,但在靠近最大输出电流下的压差会增加。对于必须保证在高负载下稳定输出的场合,应预留足够的输入电压裕量或使用大电容缓冲瞬态。

五、热性能与功率考量

线性稳压器的耗散功率由 Pd = (Vin - Vout) × Iout 决定。举例说明:若输入为 5V,输出 3.3V,差压 1.7V,在满载 100mA 时器件功耗约为 0.17W。SOT-23 封装的散热能力有限,实际允许的输出电流会随封装散热条件和环境温度变化而降低。设计时应注意:

  • 将 Vin - Vout 控制在较小范围内以降低功耗与结温升高;
  • 在 PCB 上增加铜箔面积或散热通道以改善散热;
  • 在高温环境或连续大电流工况下进行热仿真与热限流设计。

六、封装与引脚信息

HT7533 提供 SOT-23 小体积封装,适合自动化贴装生产。SOT-23 的小尺寸利于空间受限的终端产品设计,但也对散热提出更高要求。引脚功能通常包括输入(VIN)、输出(VOUT)和地(GND);实际引脚定义请参照厂家完整数据手册以获得准确的引脚排列与推荐外接元件布局。

七、总结

HT7533 是一款面向低功耗、体积受限应用的 3.3V 固定输出 LDO,凭借 1.5µA 的超低静态电流和极小的轻载压差,特别适合电池供电、长待机的物联网与便携设备。设计时应关注输入电压裕量、输出去耦电容的选择以及 SOT-23 的散热限制,以发挥器件在功耗与尺寸上的优势。欲获得完整电气特性、引脚定义与典型应用电路,请参考 GOODWORK 官方数据手册。
