LD1117DT50CTR产品概述
一、产品简介
LD1117DT50CTR 是一款由意法半导体 (STMicroelectronics) 生产的线性稳压器，属于 LDO（低压差线性稳压器）的系列产品。其设计旨在为各种电子设备提供稳定的电源电压，确保系统在恶劣环境下仍能高效工作。此款 LDO 的固定输出电压为 5V，最大输入电压可达 15V，适用于许多消费电子、工业控制和汽车电子等应用领域。
二、核心特点
输出类型与电流能力：LD1117DT50CTR 提供固定的 5V 输出电压，支持最大输出电流为 800mA。这意味着在负载需求较高的情况下，稳压器能够保持稳定输出，是功率需求较为紧张场合的理想选择。
压降与输入电压：该稳压器的最大的压降为 1.3V@800mA，这意味着在负载电流达到最大时，输入电压与输出电压之间的差异限制在 1.3V内。这一特性使其在电源设计中具有较高的灵活性，确保，即使在接近输出电压的情况下也能有效工作。
静态电流与效率：其静态电流（Iq）为 10mA，表明在无负载情况下，电源消耗相对较低，有利于在电池供电等场合实现更好的能量效率。
工作温度范围：LD1117DT50CTR 的工作环境温度范围为 -40℃ 到 125℃，这使其适合在极端温度下操作，满足了工业和汽车等应用对温度稳定性的需求。
超温与过流保护：内置的保护功能，包括过流和超温保护，确保了芯片在异常情况下不被损坏，提高了系统的可靠性和安全性。
PSRR（电源纹波抑制比）：达到了 75dB（120Hz），这一指标反映了芯片在输入信号中对纹波的抑制能力，确保输出电压在各种工作条件下保持纯净和稳定。
三、封装与安装
产品采用表面贴装型 DPAK 封装类型。其封装尺寸适合在空间受限的PCB中设计，同时提升了散热性。DPAK结构提供了良好的散热性能，这在高电流应用中尤为重要，有利于降低工作温度，提高稳定性。
四、应用领域
LD1117DT50CTR 广泛应用于以下领域：
- 消费电子：如移动设备、家用电器等，要求高效稳定的电源。
- 工业控制：PLC、传感器及其他控制程序中，提供电源稳定性和可靠性。
- 汽车电子：如汽车导航仪、车载系统等，对温度与供电稳定性要求较为严格的场合。
五、总结
LD1117DT50CTR 是一款性能优异的线性稳压器，凭借其稳定的输出电压、较高的电流输出能力、良好的温度特性以及众多内置保护功能，适用于多种电子设备和应用。意法半导体所提供的高质量和可靠性，使其成为设计工程师在选择线性稳压器时的优先选择。此款稳压器凭借其良好的性价比与多样化的应用前景，将继续在电子市场占有一席之地。

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.
