MIC29302S/TR 产品概述

一、产品简介

MIC29302S/TR 是华冠(HGSEMI)推出的一款高性能可调线性稳压器(LDO),单通道正极输出,最大输出电流可达 3A,适用于对噪声和瞬态响应有较高要求的电源系统。器件封装为 TO-263-5,工作温度范围宽,可靠性高,适合工业级应用。

二、主要特性

  • 可调输出:输出电压可通过外部分压器在 1.24V~15V 之间设置,内部基准电压约为 1.24V。
  • 使能控制:带使能(EN)引脚,可实现电源开关控制与系统节能。
  • 保护功能:内置过热保护与过流限制,增强系统可靠性。
  • 低压差:在最大输出电流 3A 时典型压差仅 450mV(Dropout)。
  • 低噪声:典型输出噪声约 400 μVrms。
  • 额定工作电压:工作电压 16V(器件最大输入电压/工作电压等级请参考详细规格书)。
  • 工作温度:-40℃ ~ +125℃。单输出、正极输出结构。

三、电性能要点

  • 输出电流:最大 3A 连续输出(注意热耗散限制)。
  • 输出电压范围:1.24V 至 15V,可通过外部电阻分压精确设定。
  • 压差性能:450mV @ 3A,适合低压差供电场合。
  • 噪声水平:约 400 μVrms,适合模拟与数字混合电路对噪声较敏感的供电。

四、封装与热管理

  • 封装:TO-263-5(表面可焊大功率封装),便于 PCB 散热。
  • 热设计:功耗 Pd = (Vin - Vout) × Iout;在高电流或大压差情况下需充分考虑 PCB 散热、热垫或外加散热片,以避免触发过热保护并保证长期可靠性。

五、典型应用

  • 工业控制与数据采集模块电源
  • 通信设备、基站辅助电源
  • 模拟前端、传感器供电(需低噪声)
  • 单板计算与嵌入式系统稳压模块

六、使用建议

  • 输出稳定与抑制振荡:建议在输入/输出端加适当的低 ESR 电容并靠近引脚布局,以保证环路稳定性与抑制瞬态。
  • 设定输出:用高精度分压电阻设定输出电压,注意电阻容差对精度的影响。
  • 使能逻辑:EN 引脚通常为高电平有效或具体逻辑请参阅数据手册,避免在不稳态时加载负载。
  • 保护与测试:在设计中预留热限与过流余量,进行热仿真和实际功率测量验证。

七、总结

MIC29302S/TR 是一款面向中高电流、低压差、低噪声要求的可调线性稳压器,兼具使能控制与完善的保护功能,适合在需可靠散热与稳定输出的工业与通信应用中使用。有关引脚定义、典型外接电路与详细限制条件,请参考华冠(HGSEMI)官方数据手册以获取完整设计指导。

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
