RP112N331D-TR-FE 产品概述

一、产品简介

RP112N331D-TR-FE 是 NISSHINBO 推出的低压差线性稳压器(LDO),输出固定 3.3V,面向低功耗、低噪声电源设计场景。器件集成电压基准、误差放大器、输出电阻分压、限流与使能电路,提供高精度稳压、超低静态电流及优良的纹波抑制性能,适合对噪声与电源干扰敏感的模拟、射频及微控制器供电应用。

二、主要特性

  • 输出极性:正极,固定输出 3.3V
  • 工作电压:最大 5.25V(输入端)
  • 最大输出电流:150 mA
  • 压差(Dropout):200 mV @ 150 mA
  • 静态电流(Iq):75 μA(典型,空载静态消耗低)
  • 输出噪声:10 μVrms
  • 电源纹波抑制比(PSRR):80 dB @ 1 kHz;10 kHz 时约 75 dB;100 kHz 时约 65 dB
  • 功能:芯片使能(EN)控制、短路保护
  • 工作温度范围:-40 ℃ ~ +85 ℃(Ta)
  • 输出通道:单通道,固定输出类型
  • 封装:SOT-23-5

三、电气与可靠性要点

  • 在最大输入 5.25V、输出 3.3V、满载 150 mA 条件下,器件功耗约为 (5.25 − 3.3) × 0.15 ≈ 0.29 W,设计 PCB 布局时需考虑散热路径与温升,SOT-23-5 封装对环境温度与铜箔散热较敏感。
  • 压差仅 200 mV(满载),适于低压差供电场合,可在较小输入裕量下维持输出稳定。
  • 高 PSRR 与低噪声特性使其适用于敏感模拟前端、RF 前端或 ADC/DAC 供电,能有效抑制来自开关电源的干扰。

四、典型应用场景

  • MCU、传感器与外围模拟电路的 3.3V 供电
  • 对噪声和纹波敏感的模拟/射频前端
  • 电池供电设备和便携式产品(低静态电流有利于待机功耗)
  • 工业控制与通信终端的局部稳压

五、使用建议与注意事项

  • 建议在输入端与输出端分别放置旁路电容(例如 1 μF ~ 10 μF 陶瓷电容),靠近引脚布板以改善稳定性与瞬态响应。具体电容值与 ESR 要求请结合系统验证。
  • 启用使能引脚可实现快速上下电管理,系统设计时需确保 EN 电平与 MCU 或控制逻辑相匹配,避免上电时的非期望状态。
  • 设计时应评估最大功耗情况下的结温与周边温升,必要时增大铜箔面积或采用热过孔以提升散热能力,确保在高环境温度下仍满足规格。
  • 短路保护提供器件自保护能力,但不建议长期在短路状态下工作,应保证系统有适当的故障检测与恢复策略。

六、封装与订购信息

  • 品牌:NISSHINBO
  • 型号:RP112N331D-TR-FE
  • 封装:SOT-23-5
  • 单通道、固定 3.3V 输出,具使能与短路保护功能。订购与使用前建议参照厂家完整数据手册与典型应用电路以获得详细引脚定义、上电时序及外部元件建议。

如需我为该器件绘制典型应用电路原理框图、计算热设计裕量或给出 PCB 布局建议,可提供输入电压范围与实际工作电流等系统信息进行进一步优化。

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
