WL2817DA33-8/TR 是 WILLSEMI(韦尔)推出的一款低压差线性稳压器,固定输出 3.3V,面向空间受限且对噪声和纹波敏感的电源场合。器件提供高达 500mA / 1A 等级的输出能力(视具体型号),输入最高工作电压 5.5V。封装为紧凑的 DFN1612-8,适合便携和嵌入式系统使用。
WL2817DA33-8/TR 在关键指标上表现出色:极低的压差在电源电压不足时仍能维持稳定输出;较低的静态电流配合使能控制,便于实现省电策略;高 PSRR 与低输出噪声使其成为对模拟与射频前端敏感的系统(如传感器采集、电台/射频模块、ADC 参考电源等)的理想后级稳压器。
DFN1612-8 小尺寸封装占板面积小、热阻低,适合高密度设计。WL2817DA33-8/TR 集成过流与过热保护,提高系统可靠性。实际设计时应参考厂方完整规格书以确认各项极限值、外部元件要求及温度漂移特性。
总结:WL2817DA33-8/TR 以其低压差、低噪声、低静态电流和完整的保护功能,适用于对噪声和效率有较高要求的嵌入式与便携式应用,是实现稳定 3.3V 电源的可靠选择。若需器件脚位图、典型应用电路或 PCB 参考设计,请参考官方数据手册或提供进一步的系统参数以便给出针对性建议。

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.
