ZD1117ILTR33 线性稳压器产品概述
一、产品定位与核心功能
ZD1117ILTR33是澜智（Zetta）推出的固定输出型线性稳压器，主打工业级可靠性与中低功率电源转换需求，属于ZD1117系列的3.3V输出型号。其核心功能是将16V以内的输入电压稳定转换为3.3V直流输出，同时内置双重保护机制，确保负载电路在恶劣工况下安全运行。
二、关键电气参数解析
该器件的核心参数直接决定应用适配性，需重点关注以下几点：
- 输出特性：固定输出电压3.3V（单通道正极输出），最大输出电流1A，可覆盖多数MCU、传感器、通信模块的供电需求；
- 输入与压差：最大工作电压16V（输入上限），满载压差1.5V@1A（即输出1A时，输入仅需比输出高1.5V，输入范围约4.8V~16V），降低了输入电源的电压要求；
- 静态电流：稳定工作时静态电流5mA，虽非超低功耗，但符合工业级器件的持续工作需求；
- 保护机制：内置过热保护（结温超阈值自动关断，回落恢复）和过流保护（输出电流超限限流），双重防护避免负载短路/过载损坏；
- 温度范围：结温工作区间-40℃~+125℃，满足工业级环境（低温户外、高温控制柜）的宽温要求。
三、封装与可靠性设计
ZD1117ILTR33采用SOT-223-4封装，具备以下优势：
- 体积紧凑：贴片式设计节省PCB空间，适配高密度电路布局；
- 散热能力：引脚自带散热面积，配合PCB铜箔铺地可有效散发热量（压差较大时需增加铜箔面积）；
- 抗振性：贴片焊接可靠性高，适合车载、工业等振动场景。
四、典型应用场景
结合参数特性，该器件主要适用于：
- 工业控制：PLC模块、传感器接口、电机驱动辅助电源（需宽温稳定供电）；
- 车载电子：车载显示屏、ADAS辅助模块、通信设备（耐受-40℃低温与发动机舱高温）；
- 通信设备：小型基站、路由器、交换机的辅助电源（1A以内供电需求）；
- 消费电子：智能家居控制器等需稳定3.3V的设备（需注意静态电流是否适配待机需求）。
五、应用注意事项
为确保稳定工作，需注意：
- 滤波设计：输入并联10μF电解电容+0.1μF陶瓷电容，输出并联同规格电容，滤除纹波；
- 压差控制：避免输入电压过高（如16V输入时，压差达12.7V，损耗12.7W），需通过散热铜箔（≥10cm²、2oz铜厚）或小型散热片散熱；
- 电压电流限制：输入不超16V，输出不超1A，防止器件损坏；
- 温度监控：结温不超125℃，实际环境温度需留有余量（如高温场景需加强散热）。
ZD1117ILTR33凭借宽温范围、双重保护与紧凑封装，成为工业、车载等领域3.3V供电的实用选择。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
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.
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.
