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:
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。
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)。
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。

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.
