REF3033AIM3/TR 产品概述

一、产品简介

REF3033AIM3/TR 是华冠(HGSEMI)推出的一款低漂移、低功耗、小封装的串联型固定电压基准器件,输出稳压 3.3V,适用于对精度与稳定性有较高要求的便携及工业级电子系统。器件工作电压范围 2.7V~5.5V,静态电流仅 300µA,封装选用紧凑的 SOT-23-3,便于空间受限的应用。

二、主要规格亮点

  • 输出类型:固定(3.3V)
  • 输出电压精度:±0.15%
  • 温度系数:30 ppm/℃(典型低漂移特性)
  • 输入工作电压:2.7V~5.5V
  • 可驱动负载电流:最高 5mA(适合参考源与小信号驱动)
  • 电压基准类型:串联(series)
  • 静态电流 (Iq):300µA(低功耗,利于电池供电系统)
  • 低频噪声(0.1Hz–10Hz):66µV p-p(优良的低频噪声性能)
  • 工作温度范围:-40℃~+125℃
  • 封装:SOT-23-3,型号:REF3033AIM3/TR(带卷带包装)

三、典型应用场景

  • 精密 ADC/DAC 参考源
  • 传感器前端与数据采集系统
  • 便携式及电池供电的测量设备
  • 工业控制与过程测量(需宽温度范围)
  • 通信设备与参考电压基准需求场合

四、产品优势

  • 高精度:±0.15% 的输出初始精度可减少后端校准工作量,提升系统测量精度。
  • 低温漂:30 ppm/℃ 的温度系数确保在温度变化下输出稳定,有利于长期漂移控制。
  • 低功耗小封装:300µA 的静态电流与 SOT-23-3 封装兼顾了功耗与 PCB 节省,适合便携设计。
  • 低噪声:0.1Hz–10Hz 范围内 66µV p-p 的低频噪声对低频测量系统尤其重要,能降低 1/f 噪声对精度的影响。

五、设计与布局建议

  • 输入去耦:在器件 VIN 与地之间放置一枚 0.1µF 陶瓷去耦电容,靠近器件引脚焊盘放置以抑制高频干扰。
  • 输出去耦:为降低噪声并提高瞬态性能,可在 VOUT 与地之间并联 0.01µF–1µF 的陶瓷电容(根据系统稳定性测试选择合适容量);避免使用大等效串联电阻(ESR)过高的电容。
  • 布局要点:将参考输出尽量靠近 ADC 引脚,走短而粗的走线,单点接地或尽量避免共享高电流回流路径,以减少注入误差。
  • 负载限制:器件最大输出电流为 5mA,不适合直接驱动大容量负载或长导线驱动,必要时采用缓冲放大器或低漂移运放作为后级驱动。
  • 热管理:SOT-23-3 封装热阻相对较高,注意与热源保持距离,当工作在极限温度或高负载时评估温升对精度的影响。

六、封装与订购信息

  • 型号:REF3033AIM3/TR
  • 品牌:HGSEMI(华冠)
  • 封装:SOT-23-3,适合自动化贴装与空间受限板级设计。

总结:REF3033AIM3/TR 以其高精度、低温漂、低噪声与低功耗的特性,适合对基准源稳定性与尺寸有严格要求的应用。设计时注意去耦与布局、并根据负载需求选择合适的后级缓冲,可发挥器件最佳性能。若需进一步的电气特性曲线、引脚排列或等效电路图,请参阅华冠官方数据手册。

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
