LD39200DPUR 产品概述
产品介绍
LD39200DPUR 是由意法半导体（STMicroelectronics）生产的一款高性能线性稳压器，封装为8-VDFN形式（4x4mm）。该稳压器具有广泛的应用领域，尤其适用于对电源管理要求较高的多种电子设备，如便携式设备、消费电子、通信产品等。LD39200DPUR的优势在于其卓越的性能和灵活的输出配置，使其成为各类电子系统中不可或缺的重要元器件。
关键参数
LD39200DPUR 的基本参数如下：
- 输入电压范围：1.25V至6V，适应多种电源布局。
- 输出电压范围：可调输出范围为0.5V到4.89V，最大输出电压可达到5.75V。
- 输出电流：额定为2A，适合支持高负载情况下的稳压需求。
- 压降：在2A输出时，最大压降仅为0.11V，这使得其在保持效率方面表现出色。
- 静态电流（Iq）：仅为300µA，确保在无负载情况下的低功耗运行。
- 温度范围：该元器件能够在-40°C到125°C的宽温范围内正常工作，适合用于工业、汽车和其他极端环境应用。
保护功能
LD39200DPUR 配备了多重保护机制，包括过流保护、超温保护和反极性保护。这些功能有效防止了由于异常情况引发的电源故障，确保系统的安全性和可靠性。
噪声和电源抑制
本稳压器在电源抑制比率（PSRR）方面表现良好，PSRR在1kHz到1MHz频率范围内可达70dB至40dB，能有效滤除输入电源中的交流噪声，确保输出电压的稳定性和纯净性。这对于对噪声敏感的应用场景尤为重要。
控制特性
LD39200DPUR还支持使能控制和电源良好（PWRGD）功能，使得用户能够更灵活地管理功率供应和监控输出状态。使能功能可以在不需要输出电压时关闭稳压器，进一步降低功耗，同时电源良好指示可以帮助设计人员实时监测系统的工作状态。
应用场景
凭借其优异的性能和丰富的功能，LD39200DPUR 稳压器可广泛应用于：
- 便携式消费电子设备：如智能手机、平板电脑及可穿戴设备。
- 工业消费产品：如电机驱动器和传感器供电。
- 通信设备：如基站小型设备和移动通信模块。
- 汽车电子：在车载信息娱乐系统中应用。
结论
总之，LD39200DPUR 以其高效能、小体积、可靠的输出性能和强大的保护特性，成为了现代电源管理解决方案中重要的选择。无论是在复杂的电源环境中，还是在需要高稳定性和高效能的系统，LD39200DPUR 都能提供出色的性能，为多种电子产品的设计与实现提供了强有力的支持。
Request for quote
Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
