ZD1117ILTR50线性稳压器产品概述
澜智（Zetta）推出的ZD1117ILTR50是一款专为工业级、汽车电子及中功率便携场景设计的固定输出线性稳压器，凭借宽温范围、完善保护特性及紧凑封装，成为5V/1A供电需求的可靠选择。
一、核心定位与适用场景
ZD1117ILTR50属于固定正极单通道线性稳压器，核心定位是为中功率负载提供稳定5V直流供电。其宽温特性（-40℃~125℃结温）使其适配极端环境：
- 工业现场：户外传感器节点、PLC控制模块（耐受低温/高温、粉尘环境）；
- 汽车电子：车载显示屏、胎压监测系统（适配发动机舱高温、冬季低温）；
- 消费电子：小型充电器、便携医疗设备（兼顾体积与功率需求）。
二、关键电气参数详解
ZD1117ILTR50的参数针对实际应用做了针对性优化，核心指标如下：
- 输入输出匹配：工作电压（输入）支持16V，固定输出5V正极，无需额外调整电路，直接匹配多数5V负载（如MCU、无线模块）；
- 输出能力：持续输出电流1A，可驱动小型电机、LCD显示屏等中功率负载；
- 压差特性：1A负载下压差仅1.5V，意味着输入电压仅需6.5V以上即可稳定输出5V，适配低电压输入场景（如电池供电设备）；
- 静态电流：5mA静态电流，待机/轻载状态下不会过度消耗系统功率，提升整体能效；
- 温宽范围：结温（Tj）覆盖-40℃125℃，符合工业级（-4085℃）及汽车级（-40~125℃）温度要求，可长期稳定工作。
三、保护特性与可靠性保障
为降低系统故障风险，器件内置两大核心保护功能：
- 过流保护：当输出短路或负载电流超过额定值时，自动限制输出电流（非熔断式），避免负载损坏及器件过热；
- 热关断：结温超过阈值（与125℃温宽匹配）时，主动关断输出；温度下降至安全范围后，自动恢复正常工作，无需人工干预。
这些特性可有效延长器件及负载的使用寿命，适配恶劣工况下的长期运行。
四、封装与应用优势
ZD1117ILTR50采用SOT-223-4封装，该封装兼具以下优势：
- 紧凑体积：贴片式设计，占用PCB面积小（约3mm×3mm），适合小型化设备布局；
- 散热性能：自带散热焊盘，可通过PCB铜箔快速散发热量，适配1A负载下的热管理；
- 生产兼容：符合标准贴片工艺，可兼容自动贴装设备，提升量产效率。
五、总结
ZD1117ILTR50以稳定5V/1A输出、宽温可靠性、紧凑封装为核心优势，覆盖工业、汽车、消费电子等多领域的中功率供电需求，是替代传统线性稳压器的实用选择。

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.
