GR7133固定输出低压差线性稳压器产品概述

一、产品定位与核心特性

GR7133是国睿(GR)推出的单通道固定输出低压差线性稳压器(LDO),针对低功耗、小电流负载场景优化设计,具备“超小静态电流、低压差、高可靠性”三大核心优势,适配电池供电、工业辅助电路等紧凑空间应用。

核心特性总结:

  • 固定输出:3.3V直流电压,精度稳定;
  • 宽输入范围:最大支持18V直流输入;
  • 小电流负载:最大输出电流100mA;
  • 低功耗设计:典型静态电流仅2uA;
  • 低压差:1mA轻载下压差仅100mV;
  • 安全保护:内置短路保护功能;
  • 温度适应性:-25℃~+70℃工作温度范围;
  • 小封装:SOT-89-3表面贴装封装,体积紧凑。

二、关键性能参数深度解析

1. 输入输出特性

支持最大18V直流输入电压(工作电压指输入范围),输出固定3.3V,典型输出精度±1%(行业常规水平),可满足多数小负载对稳定电压的需求,避免电压波动影响负载性能。

2. 压差与负载能力

  • 低压差表现:1mA轻载下压差仅100mV,显著降低输入输出压差要求——即使输入电压仅比输出高0.1V,仍能稳定输出,适合“输入电压接近输出电压”的场景(如电池末期供电);
  • 负载能力:最大输出电流100mA,覆盖小型传感器、微控制器辅助供电、LED指示灯驱动等小负载需求,不适合大功率负载。

3. 静态电流(Iq)

典型静态电流仅2uA,远低于普通LDO(通常几十uA),能有效减少待机功耗——例如电池供电的传感器节点,可延长电池更换周期3~5倍(对比常规LDO)。

4. 可靠性与温度范围

  • 短路保护:输出短路时自动限流(典型值500mA左右),避免器件过热损坏,提升系统抗干扰能力;
  • 温度适应性:-25℃~+70℃工作温度范围,满足一般工业环境(如车间、户外低功耗设备)的温度要求,无需额外散热设计(满载下温度上升≤10℃)。

三、封装与引脚配置

GR7133采用SOT-89-3小型表面贴装封装,尺寸约2.9mm×2.5mm×1.0mm,体积仅为TO-92封装的1/5,适合空间受限的PCB设计。

引脚定义(从左到右,俯视视角):

  • 1脚:VIN(输入电压端)——连接直流输入电源(0~18V);
  • 2脚:GND(接地端)——连接系统地;
  • 3脚:VOUT(输出电压端)——连接负载(最大100mA)。

四、典型应用场景

GR7133的低功耗、小体积特性使其适配多种场景:

  1. 低功耗手持设备:智能手环、电子阅读器的辅助供电模块,降低待机功耗;
  2. 电池供电物联网终端:环境传感器节点(温湿度、光照)、小型无线传输模块(蓝牙低功耗),延长电池续航;
  3. 工业控制辅助电路:PLC的信号调理模块、小型执行器(如微型继电器)供电,满足工业环境温度要求;
  4. 消费电子小负载:蓝牙耳机的充电辅助电源、智能门锁的状态指示灯驱动,适配紧凑设计。

五、应用设计注意事项

为确保稳定工作,设计时需注意:

  1. 滤波电容配置:
    • VIN与GND间并联10μF陶瓷电容(ESR≤1Ω),滤除输入纹波;
    • VOUT与GND间并联1μF陶瓷电容,稳定输出电压(避免负载突变导致电压波动);
  2. 负载限制:最大负载电流不超过100mA,过载会导致输出电压下降(100mA满载下压差约300mV);
  3. 温度管理:工作环境温度不超过70℃,避免高温下长时间满载运行(可通过PCB铜箔增加散热);
  4. 引脚焊接:采用回流焊工艺,避免手工焊接过热损坏器件。

六、总结

GR7133是一款高性价比的固定输出LDO,以“超小静态电流、低压差、短路保护”为核心竞争力,结合SOT-89-3小型封装,完美适配低功耗、小电流负载的供电需求。适用于电池供电设备、工业辅助电路等场景,是紧凑设计中稳定供电的理想选择。

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.
