产品概述:LD2981CU50TR

LD2981CU50TR 是由意法半导体(STMicroelectronics)推出的一款高性能线性稳压器(LDO),它专为提供稳定且精确的输出电压而设计,主要适用于各种电子设备中的电源管理模块。该器件具有固定的输出电压以及简易的设计方案,适合广泛的应用场景。

基本参数

LD2981CU50TR 提供的固定输出电压为 5V,最大输入电压可高达 16V,设计时为确保其长期稳定性,该稳压器的最大输出电流为 100mA。同时,设备在负载为 100mA 的情况下,输出电压降不超过 0.375V,这使得该稳压器在不同负载下也能够维持较好的输出性能。

该稳压器的静态电流(Iq)为 150µA,相对较低的静态电流有助于提高整体能效,特别在功耗敏感的应用中,能够延长电池使用寿命。LD2981CU50TR 的最大供电电流为 2.6mA,这也符合低功耗设备的设计要求。

电气性能

该 LDO 的失拨抑制比(PSRR)为 63dB(1kHz),这个值表明了它在输入电压波动或噪声情况下,能够良好地隔离这些干扰,确保输出电压的稳定。这一特性对于敏感的模拟电路及 RF 应用尤其重要,因为它能够保证在电源波动时,依然提供清晰的信号。

保护功能

LD2981CU50TR 内置多种保护功能,包括过流保护和超温保护。这些功能有效保护了器件及其使用的电路板,避免由于意外故障造成的损坏。此外,这些保护特性使得设备在不同工作环境下更加可靠,能够承受外部条件的变化。

温度范围

该稳压器的工作温度范围为 -40°C 到 125°C,使其适合在各种严苛的环境中运行。从消费电子产品到工业控制系统,LD2981CU50TR 的优越温度性能增强了其适用性,能够支持各种长期可靠的应用。

封装与安装

LD2981CU50TR 采用 SOT-89-3 封装,尺寸紧凑,非常适合于空间有限的PCB设计。表面贴装型的安装方式使其非常适用于自动化生产,降低了生产成本并提高了生产效率。该封装的一体化设计,也有助于提高散热性能,进一步提升器件的稳定性。

应用领域

LD2981CU50TR 适用于多个应用领域,包括但不限于便携式设备、电池供电产品、微控制器、电机驱动器、RF和模拟信号处理等场合。其在移动设备和物联网(IoT)设备中的应用尤其广泛,因其能够有效地管理电能并确保稳定的电源输出。

总结

LD2981CU50TR 线性稳压器的设计充分考虑了其在广泛应用场景中的适用性和可靠性。凭借稳定的输出性能、优秀的电气特性、内置保护功能及广泛的工作温度范围,该产品无疑是开发电源管理解决方案中的一款理想选择。无论是在消费类电子产品还是工业设备中,LD2981CU50TR 都展现出了其作为高性能LDO的专业性与可靠性。通过选择LD2981CU50TR,设计工程师能够更有效地实现其电源设计目标,推动电子产品的创新和发展。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
