NCP114ASN300T1G 是一款由安森美半导体(ON Semiconductor)生产的高性能线性稳压器,适用于各种电源应用,特别是在需要稳定电压输出的电子设备中。该稳压器具有固定输出电压,设计时考虑了在工业及消费电子环境中的广泛应用,从而实现高效的电源管理和系统稳定性。
NCP114ASN300T1G 的主要输出配置为正输出,输出电压固定为 3V,能够满足大多数低电压数字电路的需求。超过该范围的输入电压会影响稳压器的性能,但其最大输入电压可达到 5.5V,这使得该稳压器在许多应用中具有灵活性。
在电压降方面,NCP114ASN300T1G具有相对较低的电压降,能够在多种负载条件下提供稳定的输出电压,从而确保负载端设备的可靠运行。
该稳压器在 PSRR(电源抑制比)方面表现出色,达到 75dB(在 1kHz 下),这意味着它能够有效地抑制输入电压变化的影响,提供更加平稳的输出电压。此外,该器件的温度工作范围为 -40°C 至 85°C,使其适合于严苛的应用环境,例如汽车、工业控制和消费电子产品。
该稳压器还具备多种保护特性,包括过流保护和过温保护,这些功能确保了设备在异常条件下的安全性和可靠性。这对于长时间运行和高可靠性要求的应用尤其重要。
NCP114ASN300T1G 具备简便的控制特性,支持使能功能。当不需要输出电压时,只需通过控制引脚使能功能将其置于低功耗状态,从而节省能量。同时,该功能在待机模式下也是必要的,可以有效降低整机的功耗。
在物理方面,该稳压器采用了 SOT-23-5 细型封装,尺寸小巧,适合表面贴装(SMT)技术,便于在现代紧凑型电子产品上安装。其 TSOP 封装设计使得 NCP114ASN300T1G 能够在空间受限的应用场景中实现高效电源管理。
NCP114ASN300T1G 可以广泛应用于以下场景:
综上所述,NCP114ASN300T1G 线性稳压器凭借其小巧的封装、出色的电源抑制比、可在恶劣环境下运行以及具有多种保护功能,成为多种电子产品设计的理想选择。通过提供稳定的 3V 输出电压及 300mA 输出电流,NCP114ASN300T1G 能够有效满足许多现代电源管理应用的需求,是设计人员值得信赖的电源解决方案之一。

Use the form for single models, category sourcing, and multi-line BOM requirements.
Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
