RT9080-33GJ5 产品概述

一、产品简介

RT9080-33GJ5 是一款小尺寸、低静态电流的固定输出线性稳压器(LDO),输出为正向 3.3V,单通道设计,封装为 SOT-23-5。器件集成使能控制与过热保护,适合对功耗、噪声和纹波抑制有较高要求的便携与嵌入式系统。品牌为 TECH PUBLIC(台舟电子)。

二、主要规格亮点

  • 输出电压:固定 3.3V
  • 输出电流:最大 600mA
  • 工作/输入电压:最高 5.5V(器件允许的工作电压上限)
  • 压降(Dropout):320mV @ 600mA(在满载时低压差特性)
  • 静态电流(Iq):约 2μA(待机超低电流,适合电池供电)
  • PSRR:75dB @ 1kHz(对电源纹波抑制能力强)
  • 输出噪声:50μVrms(低噪声输出,利于模拟与射频前端)
  • 保护与控制:带使能引脚与过热保护(热关断)
  • 工作温度范围:-40℃ ~ +85℃(Ta)
  • 封装:SOT-23-5(适合面积受限的板级设计)

三、电气与热设计要点

  • 最低输入电压:使用时,应保证 VIN > VOUT + 压差;以 3.3V 输出并在 600mA 时为准,VIN 最低约 3.3 + 0.32 ≈ 3.62V。若系统存在较大输入纹波或瞬态要求,应留有裕量。
  • 功耗与散热:功耗 P = (VIN − 3.3V) × IOUT。举例 VIN=5V、IOUT=600mA 时,P ≈ 1.02W;在 SOT-23-5 小封装下需通过 PCB 铜箔散热与良好散热布局避免过热触发热关断或温升过高。
  • 输出电容与稳定性:建议使用低 ESR 陶瓷电容(X5R/X7R),典型配置为输入侧 1μF4.7μF,输出侧 2.2μF10μF(具体按器件应用说明书确认稳定区间与 ESR 要求)。电容应尽量靠近引脚放置,走线短且粗。
  • 使能与启动:使能引脚可用于软启动、待机控制和系统上电序列管理;禁能时静态电流极低,有助于节能。使能极性和逻辑电平参考器件规格手册设置。

四、典型应用场景

  • 便携式电池供电设备(低静态电流利于延长待机寿命)
  • 单片机供电与外围模拟/射频前端(高 PSRR 与低噪声抑制干扰)
  • 工业控制模块、传感器前端与通信终端(需要稳定的 3.3V 电源与过热保护)
  • 面板、摄像头、音视频设备的局部稳压电源

五、使用建议与注意事项

  • 布局:输入/输出电容尽量靠近 LDO 引脚,输入侧需有适当去耦,地线采用回流地或星形地以减少噪声回流干扰。
  • 热管理:在高电流或高差压场景下增加 PCB 散热铜面积,或在必要时降低负载电流以避免触发过热保护。
  • 测试:在目标应用条件(VIN 最大、环境温度上限、持续负载)下验证温升与长期稳定性。
  • 资料参考:器件详细引脚定义、使能极性、启动特性与电容稳定性等请参阅厂方数据手册以获得完整设计约束与典型应用电路。

总体而言,RT9080-33GJ5 以其低静态电流、较高的输出电流能力、优良的 PSRR 与低噪声特性,适合对电源质量和能耗有要求的空间受限应用。合理的热设计与电容选型可发挥其最佳性能。

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
