ZD1117ILTR18 线性稳压器产品概述

一、产品定位与核心功能

ZD1117ILTR18是澜智(Zetta)推出的固定输出线性稳压器(LDO),核心功能是将宽范围输入电压转换为稳定的1.8V正极输出,最大支持1A负载电流,专为需要高可靠性、宽温度范围的电源转换场景设计。作为1117系列的工业级衍生型号,它集成了过流、过热保护,适配SOT-223-3小封装,可灵活嵌入各类电子设备的电源系统,无需额外外围电路即可实现稳定供电。

二、关键参数解析

ZD1117ILTR18的核心参数明确了应用边界,关键指标如下:

  • 输出特性:固定1.8V正极单通道输出,负载电流最大1A,输出精度满足常规电源需求;
  • 输入与压差:最大工作电压16V(输入电压需满足“输出电压+压差”,即最小输入3.3V@1A负载),1A负载下压差仅1.5V,减少输入电压冗余设计;
  • 静态功耗:典型静态电流5mA,平衡了效率与输出稳定性,适合中等负载场景;
  • 温度范围:结温(Tj)支持-40℃~+125℃,覆盖工业级、部分车载级环境温度需求;
  • 保护机制:内置过热保护(结温超阈值自动关断/恢复)、过流保护(负载超1A限流),无需外部保护电路。

三、可靠性与保护机制

ZD1117ILTR18的双重保护设计是核心优势:

  • 过流保护:当负载电流超过1A阈值时,芯片自动进入限流模式(输出电流限制在1.1~1.2A),防止后端负载短路或过流损坏,同时避免芯片过载发热;
  • 过热保护:结温超过150℃左右时,芯片暂时关断输出,温度降至安全范围后自动恢复,有效避免高温环境下的永久损坏。这两个保护机制无需额外设计,简化了系统BOM成本。

四、封装与典型应用场景

  • 封装优势:SOT-223-3封装(尺寸约6.5×3.5mm),贴片式设计节省PCB空间,且散热面积比SOT-23更大,能稳定散发布1A负载时的热量,适合高密度PCB布局;
  • 典型应用:
    1. 工业控制模块:PLC传感器供电、通信接口模块,宽温度范围适配工业现场-20℃~+85℃环境;
    2. 消费电子:便携式平板、机顶盒的CPU/内存供电,1A输出满足低功耗芯片需求,小封装适配设备轻薄化;
    3. 通信设备:路由器、交换机辅助电源,稳定1.8V输出提升设备在电网波动下的可靠性。

五、选型参考与优势总结

对比同类固定输出LDO(如经典1117系列),ZD1117ILTR18的优势在于:

  • 宽温适配:-40℃+125℃结温,比商业级(0℃70℃)更适配 harsh 环境;
  • 保护齐全:内置过流、过热保护,无需额外电路;
  • 散热可靠:SOT-223封装支持1A负载长期稳定工作;
  • 品牌可靠:澜智工业级测试保证产品一致性,降低批量应用风险。

应用注意:需确保输入电压≥3.3V(1A负载下),PCB布局预留散热空间,避免结温过高触发保护。

该产品以高可靠性、小封装、宽温度范围为核心卖点,适合工业、消费电子、通信等多领域的低压稳定供电需求。

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
