RP114N331D-TR-FF 产品概述

一、产品简介

RP114N331D-TR-FF 是 NISSHINBO 推出的一款固定输出、带使能功能的线性稳压器(LDO),采用 SOT-23-5 小型封装,面向对低噪声、高抑制比和低功耗有要求的便携及嵌入式系统电源管理场景。该型号提供 3.3V 固定输出,最大输出电流可达 300mA,工作环境温度范围为 -40℃ 到 +85℃(Ta)。

二、主要特性

  • 输出类型:固定(3.3V)
  • 输出极性:正极
  • 最大输出电流:300mA
  • 典型压差(Dropout):220mV @ 300mA
  • 工作电压/最大输入:5.25V(建议参考数据手册确认输入范围)
  • 静态电流(Iq):50μA(静态/待机模式下低功耗)
  • 使能功能:带 EN 引脚,支持远程开/关
  • 过流保护(OCP):内置限流保护,提升系统可靠性
  • PSRR(电源纹波抑制比):75dB @ 1kHz,高抑制能力
  • 输出噪声:75μVrms(典型)
  • 封装:SOT-23-5,便于空间受限系统布局

三、电气性能要点

  • 低压差:在 300mA 负载时仅约 220mV 的压差,使其在低压差工作条件下仍能提供稳定 3.3V 输出,有利于提高电源效率与热性能。
  • 高 PSRR:75dB@1kHz 的抑制能力对抑制开关电源或其他噪声源的纹波非常有效,适合噪声敏感的模拟前端或 RF 前置电路。
  • 低噪声:75μVrms 的输出噪声适合对噪声敏感的传感器、ADC、时钟等电路。
  • 低静态电流:50μA 的待机电流帮助延长电池供电的系统寿命,适合便携设备与 IoT 节点。
  • 保护功能:内置过流保护,发生异常负载时能限制输出电流,保护稳压器与负载元件。

四、典型应用场景

  • 便携式设备与电池供电系统(传感器节点、手持终端)
  • MCU / SoC 的 3.3V 电源轨
  • 模拟前端与 ADC 供电(需低噪声、高 PSRR)
  • 无线模块与通信设备的电源管理
  • 工业控制与测量设备(工作温度范围宽)

五、封装与典型引脚说明

封装:SOT-23-5(小型、低占板面积) 典型引脚功能(仅供参考,具体管脚定义请以厂商最终数据手册为准):

  • EN(使能):高电平使能输出,低电平关断
  • OUT(输出):稳压 3.3V 输出
  • GND(地):电源与信号地
  • IN(输入):接入电源(最高参考 5.25V)
  • NC/保留:厂商可能保留或用于热/检测试验

六、应用建议与注意事项

  • 输入/输出电容:为保证稳定性,建议按照数据手册配置适当类型与容量的输入/输出旁路电容,注意输出电容的 ESR 要求。
  • 散热与热路径:在大负载或高环境温度下注意封装散热,合理布局地平面和热沉路径以防温升触发热关断。
  • 使能控制:EN 引脚可用于节能模式,建议在系统上电顺序中考虑 EN 与其他电源轨的关系。
  • 布局建议:靠近稳压器布置输入/输出电容与负载,缩短关键回路,改善 PSRR 与噪声性能。

总结 RP114N331D-TR-FF 以其低压差、高 PSRR、低噪声与低静态电流的综合特性,适合对电源质量和能耗有严格要求的便携与嵌入式应用。使用时请参考 NISSHINBO 的完整数据手册以获取详细电气特性、引脚定义和外部元件推荐,确保在目标应用中获得最佳性能与可靠性。

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
