LR1801G-33-SH2-R 是 UTC(友顺)推出的一款固定输出线性稳压器(LDO),输出电压为 3.3V,面向对噪声、稳定性和效率有较高要求的嵌入式与工业级应用。器件采用 HSOP-8-EP 封装,集成过流保护,额定输出电流 1A,适用于工作温度范围 -40℃ 到 +125℃(Tj)。
LR1801G-33-SH2-R 在满载 1A 时压差仅约 230mV,意味着在输入电压略高于 3.53V 时仍能维持稳定 3.3V 输出。60µA 的低静态电流有助于降低空载或待机功耗;60dB 的 PSRR 在 1kHz 下能显著抑制来自开关电源或其他干扰源的纹波。
HSOP-8-EP 封装自带外露焊盘(EP),有利于热量从芯片导出。建议在 PCB 上布置大面积接地/散热铜箔并可靠焊接外露焊盘,以降低结壳温升并提升长时间大电流工作时的稳定性。

Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
