ZD1117ILTR331是澜智(Zetta)推出的固定输出型低压差线性稳压器(LDO),专为需要稳定3.3V电源、且对效率和空间有要求的电子系统设计。其核心参数覆盖宽电压范围、大输出电流及工业级温度适应性,同时集成双保护功能,可满足多种场景的可靠性需求。
该芯片的核心定位是中小功率固定3.3V电源转换,重点解决“输入电压 margin 小”“空间紧凑”“宽温环境”下的电源稳定问题。关键特性包括:
静态电流(Iq)为2mA,属于LDO中的中等水平——既保证了输出稳定性,又避免了极端低Iq芯片的输出纹波或响应速度问题。在轻载(如10mA)时,效率约为3.3V/(输入电压),满载时效率约为3.3V/(3.3V+1.3V)=71.7%,适合对效率要求不极端但需要稳定输出的场景。
ZD1117ILTR331采用SOT223封装,是一款小型表面贴装封装(尺寸约6.5mm×3.5mm),具有以下优势:
该芯片可广泛应用于以下场景:
ZD1117ILTR331以“高性价比+稳定可靠”为核心优势,适合对电源稳定性要求较高、但预算有限的中小功率电子系统。其集成的保护功能和宽温范围,可有效降低系统故障率,减少后期维护成本。

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.
