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。
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。
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。
GR6220B331MR-G的特性使其适配多种低功耗、小型化场景:
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:
相比同类3.3V固定输出LDO,GR6220B331MR-G具备以下核心优势:
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。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
