HT7533S 产品概述

一、产品简介

HT7533S 是华轩阳电子(HXY MOSFET)推出的一款高输入压差、超低静态电流的线性稳压器(LDO)。该器件为固定输出型,输出电压为 3.3V,单通道正极输出,封装为常用的 SOT-23 小型封装,适合空间受限且对静态功耗有严格要求的便携与工业应用。

二、主要参数

  • 输出类型:固定(3.3V)
  • 最大工作电压(输入):30V
  • 输出电流:典型 100mA(持续)
  • 压差(Dropout):55mV @ 1mA(说明:低负载时的压差典型值;负载增加时压差会相应上升)
  • 静态电流(Iq):1.5µA(超低静态电流,适合待机/低功耗场景)
  • 工作温度范围:-40℃ ~ +85℃(Ta)
  • 输出极性:正极输出
  • 通道数:单通道
  • 封装:SOT-23

三、特点与优势

  • 超低静态电流:1.5µA 的静态电流有利于延长电池供电设备的待机时间。
  • 宽输入电压支持:最高可达 30V,适用于单电池、多级电源或汽车点火瞬态等较高输入场景(需配合输入抑制措施)。
  • 小体积封装:SOT-23 封装节省 PCB 面积,利于便携式及空间受限设计。
  • 稳定的 3.3V 输出:适配大部分数字电路与模拟前端供电。
  • 适合低功耗与中等负载:100mA 的输出能力满足传感器、MCU、无线模块在大多数工作模式下的供电需求。

四、典型应用

  • 电池供电设备(手持终端、便携式仪表)
  • 物联网终端与传感器节点(对低待机功耗有要求)
  • 工业控制与传感模块(需要宽输入电压耐受性)
  • 消费电子外围电源(外围模拟或数字子系统)

五、封装与引脚说明

HT7533S 采用 SOT-23 三引脚封装,典型功能为 VIN、GND、VOUT 三端。实际引脚编号与引脚排列请以华轩阳电子官方数据手册为准;在 PCB 布局时建议将输入/输出去耦电容尽量靠近相应引脚焊盘布局,以保证稳压器的稳定性与瞬态性能。

六、推荐外部元件与注意事项

  • 输入电容:建议在 VIN 端并联去耦电容(如 0.1µF 陶瓷)以抑制输入纹波与瞬态尖峰。
  • 输出电容:常用 1µF ~ 10µF 低 ESR 陶瓷或固体电解电容,以保证环路稳定与良好瞬态响应。具体容量与 ESR 要求请参照厂方典型应用与稳定性要求。
  • 输入浪涌保护:若应用于汽车或工业环境,建议增加 TVS 二极管或串联 RC 抑制以防瞬态过压。
  • 散热考虑:SOT-23 为小功率封装,满载时需注意功耗与结温上升;在高输入差或高负载工况下应评估封装的功耗能力并优化 PCB 热散设计。

七、热设计与可靠性

在计算功耗时需注意:P = (Vin - 3.3V) × Iout。高输入电压与高输出电流将导致显著功耗并产生热量,若功耗较大,应采取热铜箔散热、加大焊盘或降低输入电压等措施以保证器件在额定温度范围内长期可靠工作。

八、订购信息与技术支持

品牌:HXY MOSFET(华轩阳电子);型号:HT7533S;封装:SOT-23。建议在设计与批量采购前索取并阅读华轩阳电子的完整数据手册与封装资料,以获得详细的电气特性曲线、引脚图与测量条件。若有特殊环境或额外认证需求,请联系厂商技术支持获取应用指导与可靠性验证建议。

总结:HT7533S 以其超低静态电流、宽输入电压及小体积封装,适合对待机功耗有严格要求且电源输入波动较大的低功耗系统和便携设备。设计时需重视输出电容与散热布局以确保长期稳定运行。

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
