NCP110AFCT120T2G 产品概述

一、产品简介

NCP110AFCT120T2G 是 ON Semiconductor(安森美)推出的一款超低静态电流、高PSRR 的固定输出线性稳压器(LDO)。该器件提供 1.2V 正向输出,最大输出电流 200mA,输入电压至 5.5V,适用于对噪声和电源抑制有较高要求的便携与工业应用。封装为超小型 WLCSP-4(0.64 × 0.64 mm),便于空间受限的系统设计。

二、主要特性

  • 输出电压(固定):1.2V
  • 最大输出电流:200mA
  • 工作电压(输入):最高 5.5V
  • 压降(Dropout):190 mV @ 200 mA(典型)
  • 静态电流(Iq):25 μA,适合低功耗系统
  • 电源纹波抑制比(PSRR):95 dB @ 1 kHz,优异的纹波抑制性能
  • 输出噪声:8.8 μVrms,适合对噪声敏感的模拟前端与 ADC 供电
  • 保护功能:过流保护、过热保护、短路保护
  • 使能脚(EN):带使能功能,支持电源管理与电源序列控制
  • 工作结温范围:-40 ℃ 至 +125 ℃ (@Tj)

三、性能亮点与应用价值

NCP110AFCT120T2G 具有非常优秀的 PSRR 与低输出噪声,使其非常适合用于射频前端、模数转换器(ADC)、精密传感器和音频电路等对电源纯净度敏感的场合。25 μA 的静态电流结合小尺寸封装,非常适合电池供电和物联网终端等空间与能耗受限的产品。低压降(190 mV @200 mA)确保在较低差分电压下仍能提供稳定输出,提高系统效率。

四、封装与热管理

器件采用 WLCSP-4 超小型封装(0.64 × 0.64 mm),适合对 PCB 面积要求严格的便携设备。由于体积小,热阻相对较高,设计时需注意 PCB 走铜和散热通路:

  • 在 PCB 下方及周围保留并加宽接地铜箔,形成良好散热面。
  • 根据实际功耗估算结温,并在散热预算内确保器件工作在安全范围。
  • 推荐查看器件数据手册中的热阻和布局示例,采用制造商建议的焊盘与过孔布局。

五、设计与布局建议

  • 输入/输出端应并联适当的去耦电容以保证稳定性与瞬态响应,优先选择低 ESR 的陶瓷电容(具体容值与布局请参照数据手册)。
  • EN(使能)脚用于电源序列与待机控制,建议在使能路径上加入适当的上拉/下拉以确保上电状态可控。
  • 为发挥高 PSRR 性能,布线时应尽量缩短从输入到稳压器及旁路电容的走线长度,避免噪声耦合到敏感节点。
  • 在靠近稳压器的地平面实现固体接地,避免通过长回流路径引入额外噪声。

六、典型应用场景

  • 便携式与电池供电设备(传感器节点、可穿戴设备)
  • 无线与射频模块的敏感供电(VCO、LNA、射频前端)
  • 精密模拟电路与 ADC/DAC 前端电源
  • 音频电源与低噪放大器供电

七、产品优势总结

NCP110AFCT120T2G 结合了低静态电流、优秀的 PSRR 与低噪声特性,以及多重保护与使能功能,适用于对电源质量与封装面积有严格要求的现代电子系统。针对具体应用,请参考官方数据手册获取完整电气特性、外围元件推荐和布局范例,以确保系统的稳定性与可靠性。

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
