NCP114AMX280TCG 线性稳压器(LDO)产品概述

NCP114AMX280TCG是安森美(ON Semiconductor)推出的一款超小型固定输出线性稳压器(LDO),专为低功耗、紧凑空间设计的电子设备打造,具备高集成度、低噪声、宽工作温度等核心特性,可满足消费电子、可穿戴、物联网等多领域的电源稳压需求。

一、产品核心优势

该器件针对便携与低功耗场景优化,核心优势体现在:

  1. 超小封装:采用1×1mm UDFN-4-EP封装,体积仅为传统封装的1/3左右,适配极小空间的PCB设计;
  2. 低功耗表现:轻载时静态电流仅50μA,待机功耗极低,大幅延长电池续航;
  3. 稳定输出能力:300mA持续输出电流,满负载下压差仅155mV,输入电压仅需略高于输出即可稳定工作;
  4. 抗干扰与低噪声:1kHz时电源纹波抑制比(PSRR)达75dB,输出噪声低至70μVrms,适合敏感模拟电路;
  5. 完善保护机制:集成短路、过流、过热保护及使能控制,提升系统可靠性。

二、关键电气参数详解

NCP114AMX280TCG的电气参数精准匹配低功耗应用需求,核心参数如下:

  • 电压范围:输入工作电压最大5.5V,固定输出电压2.8V,输出极性为正极,单通道设计;
  • 输出能力:持续输出电流300mA,满负载(300mA)下压差仅155mV(即输入电压≥2.8V+0.155V=2.955V即可稳定输出),适配锂电池等低压电源;
  • 静态电流:典型值50μA,轻载时功耗可忽略,适合待机或低负载场景(如传感器节点);
  • 纹波与噪声:1kHz频率下PSRR达75dB,可有效抑制电源端的高频纹波;输出噪声为70μVrms,避免对音频、射频等敏感电路造成干扰;
  • 工作温度:结温范围-40℃~+85℃,适应工业级宽温环境与消费电子的高低温场景。

三、封装与物理特性

该器件采用UDFN-4-EP(1×1)封装,具体特性:

  • 封装尺寸:1.0mm×1.0mm×0.4mm(典型高度),引脚间距0.5mm,适配高密度PCB布局;
  • 暴露焊盘(EP)设计:增强散热能力,提升功率密度,避免满负载下结温过高;
  • 引脚配置:4引脚设计,分别为VIN(输入)、VOUT(输出)、EN(使能)、GND(地),功能清晰,布线简单。

四、保护特性与可靠性

NCP114AMX280TCG集成多重保护功能,保障系统稳定:

  1. 短路保护:输出端短路时自动启动限流,避免器件与负载损坏;
  2. 过流保护:负载电流超过阈值(典型350mA)时,自动限制输出电流,防止过流烧毁;
  3. 使能控制:通过EN引脚可外部控制输出开启/关闭,实现电源域的独立管理,降低待机功耗;
  4. 过热保护:结温超过150℃(典型)时,关断输出,温度回落至安全范围后自动恢复,防止过热损坏。

五、典型应用场景

凭借小封装、低功耗、高可靠性等特性,NCP114AMX280TCG广泛应用于:

  • 可穿戴电子:智能手环、智能手表、TWS蓝牙耳机(适配小空间与长续航需求);
  • 物联网传感器:环境监测节点、智能穿戴传感器(低静态电流延长电池寿命);
  • 便携式音频设备:迷你音箱、蓝牙耳机(低噪声提升音频质量);
  • 小型消费电子:智能玩具、便携式充电器(紧凑空间与保护功能适配);
  • 工业级低功耗模块:工业传感器节点、远程监测设备(宽温范围与可靠性)。

总结:NCP114AMX280TCG作为安森美推出的高性价比LDO,以超小封装、低功耗、低噪声及完善保护为核心,精准覆盖便携与低功耗应用的电源稳压需求,是消费电子、物联网等领域的理想电源解决方案。

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.

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
