GR6220B331MR-G 低压差线性稳压器(LDO)产品概述

GR6220B331MR-G是国睿(GR)品牌推出的一款固定输出型低压差线性稳压器,专为低功耗、小型化电子设备设计,具备宽输入电压范围、低静态电流、高纹波抑制等核心特性,适配多种电池供电及电源管理场景。

一、核心定位与基础特性

该产品属于单通道正极输出LDO,采用SOT-23-5小型表面贴装封装,主要面向需要稳定3.3V供电、且对功耗敏感的终端产品。其基础特性包括:固定输出电压、带使能控制引脚、宽工作温度范围,可满足常规消费类、工业辅助电路的供电需求。

二、关键性能参数深度解析

(一)电压与电流规格

  • 输入输出电压:工作电压(输入电压)支持7V以内,固定输出3.3V,输入输出压差约3.7V,可适配单节锂电池(满电4.2V)、5V USB电源、线性电源等多种输入源;
  • 输出能力:最大持续输出电流300mA,足以驱动大多数低功耗传感器(如温湿度、光照)、蓝牙模块(BLE)、小型MCU等负载;
  • 静态电流:典型值仅25μA,轻载或待机状态下功耗极低,显著延长电池供电设备的续航时间(如蓝牙信标可减少充电频率)。

(二)纹波抑制与稳定性

电源纹波抑制比(PSRR)达75dB@1kHz,可有效抑制输入电源的高频纹波(如开关电源的开关噪声),确保输出电压稳定、纯净,减少对后级敏感电路(如ADC采样)的干扰,降低额外滤波电容需求。

(三)控制与环境适应性

  • 使能功能:集成使能控制引脚,可通过外部逻辑信号(如MCU GPIO)控制芯片开关:使能有效时输出稳定3.3V,使能无效时芯片进入低功耗待机模式,进一步降低系统总功耗;
  • 工作温度:覆盖-20℃至+60℃,满足室内常规环境、一般户外场景(如智能花盆传感器)及部分工业辅助电路的温度要求。

三、典型应用场景

GR6220B331MR-G的特性使其适配多种低功耗、小型化场景:

  1. 便携式电子设备:蓝牙无线耳机、智能手环的辅助供电电路,利用低静态电流延长电池续航;
  2. 物联网终端节点:温湿度传感器、光照传感器、BLE信标等,通过使能控制实现休眠/唤醒,待机功耗可降至微安级;
  3. 小型消费类产品:智能灯泡的控制模块、小型蓝牙音箱的信号调理电路,小封装适配紧凑PCB设计;
  4. 工业辅助电路:PLC(可编程逻辑控制器)的传感器供电、小型电机驱动的辅助稳压,满足宽温度范围需求。

四、封装与引脚配置

采用SOT-23-5表面贴装封装,尺寸紧凑(约2.9mm×1.6mm),适合高密度PCB布局(如智能手表内部电路)。引脚配置符合常规5脚LDO设计逻辑(具体参考国睿官方 datasheet),通常包含:

  • VIN(电源输入)、GND(接地)、EN(使能控制)、VOUT(稳压输出)、NC(闲置引脚),方便工程师快速集成设计。

五、产品竞争优势总结

相比同类3.3V固定输出LDO,GR6220B331MR-G具备以下核心优势:

  • 低功耗表现:25μA静态电流在同类产品中处于领先水平,特别适合电池供电场景;
  • 纹波抑制能力:75dB@1kHz的PSRR确保输出纯净,减少后级滤波电容数量;
  • 灵活电源管理:集成使能引脚,支持外部逻辑控制,优化系统功耗(如MCU休眠时切断LDO输出);
  • 小型化设计:SOT-23-5封装节省PCB空间,适配微型终端产品;
  • 宽输入兼容性:7V输入范围可兼容单节锂电池、5V USB电源等多种输入源,减少电源设计限制。

该产品是低功耗、小型化电子设备稳压供电的优选方案,可有效提升系统稳定性与续航能力,适配多种主流应用场景。

Sourcing availability signal

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
