LD39050PUR 产品概述
一、产品简介
LD39050PUR 是由意法半导体（STMicroelectronics）推出的一款高性能线性稳压器（LDO），其主要用于提供稳定的电源输出，适用于各类电子设备的电源管理系统。此款LDO的输出电压可调范围较广，从0.8V到5.1V，适应了多种应用场景的需求。
二、主要特点
广泛的输入和输出电压范围
该LDO支持最高5.5V的输入电压，允许用户在多种电源条件下灵活使用。同时，其输出电压可调范围从0.8V到5.1V，这为不同设备和电路提供了更为灵活的电压选择。高输出电流能力
LD39050PUR能提供高达500mA的输出电流，适合为大部分低功耗数字电路和模拟电路供电。低压降特性
在500mA的负载条件下，最大压降为0.4V，确保了良好的电能转换效率，减少了在电源设计中的能耗和热量。静态电流与供电功耗
本产品的静态电流（Iq）为50µA，供电最大电流为200µA，这意味着其在待机状态下的功耗极低，适合电池供电的设备。良好的电源抑制比（PSRR）
LD39050PUR在1kHz到10kHz频率范围内的电源抑制比（PSRR）为62dB到65dB。这一性能使其能够有效过滤输入电源中的杂波干扰，提供更加稳定的输出电压。保护功能
该LDO集成了多种保护功能，包括过流保护、超温保护和短路保护，确保了设备在极端情况下的安全运行，大幅提高了系统的可靠性。宽温工作范围
LD39050PUR的工作温度范围为-40°C到125°C，保证了其在严苛环境下的可靠性，适用于工业、汽车和消费类电子等多种应用领域。表面贴装与封装
该产品采用6-VDFN裸露焊盘封装（DFN-6(3x3)），具备较小的尺寸和出色的散热性能，方便在现代紧凑型电路板设计中使用。
三、应用场景
LD39050PUR广泛应用于各类电子产品，例如：
- 便携式设备：如智能手机、平板电脑及可穿戴设备等。
- 消费类电子：智能家居设备、音频产品等。
- 工业控制：各种传感器、数据采集器，以及需要稳定电压源的工业设备。
- 汽车电子：车载信息系统及其他汽车控制模块。
四、总结
LD39050PUR是一款功能全面、性能稳定的可调线性稳压器，凭借其良好的电气性能和丰富的保护措施，可以在多种严苛的应用环境中提供稳定可靠的电源支持。其低功耗和广泛的输入输出电压范围使其成为各种便携式、工业和汽车应用的理想选择。意法半导体以其卓越的技术和持续的创新，为客户提供高质量、高性能的电子解决方案。
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.
