LM29150RS-3.3 产品概述

LM29150RS-3.3 是一款来自 HTC 的固定输出低压差线性稳压器,输出电压为 3.3V,面向对可靠性与简单电源设计有要求的嵌入式与工业应用。器件集成多重保护功能,封装为 TO-252-2 (DPAK),便于表面贴装与散热处理。

一、功能与主要参数

  • 输出类型:固定,输出电压 3.3V(正极输出)
  • 输出电流:最高 1.5A(稳态输出能力)
  • 工作电压:最高 26V(器件输入耐受范围)
  • 压降(Dropout):350 mV @ 1.5A(在满载时需保证 Vin ≥ 3.65V)
  • 静态电流(Iq):8 mA
  • 噪声:约 400 µVrms
  • 输出通道数:1 路

二、保护与可靠性特点

  • 过热保护(Thermal shutdown):防止器件在过热条件下持续工作导致损坏。
  • 过流保护(Current limit):限制输出电流,保护负载与稳压器本体。
  • 反接保护(Reverse-input protection):在输入反接情况下保护器件及下游电路。
  • 工作温度范围:-40℃ 到 +125℃(结温 Tj 范围),适配工业级环境。

三、封装与热管理

  • 封装:TO-252-2 (DPAK),适合表面贴装,背部大铜面可用于焊盘散热。
  • 散热建议:在高负载(接近 1.5A)或高环境温度下,应在 PCB 上设计足够的铜面积与热传导路径,必要时与散热片或大面积接地铜箔搭配使用,以降低结温并确保稳定输出。

四、典型应用场景

  • 工业控制与嵌入式设备的 3.3V 电源模块
  • 通信设备、传感器前端供电
  • 电池供电或车载电子中要求短时高电流和可靠保护的场合
  • 需要简单外部器件且关注噪声与稳定性的数字/模拟混合电路供电

五、使用建议与布局要点

  • 输入电压需高于 3.65V(含裕量时推荐 ≥ 5V)以覆盖压降与瞬态需求。
  • 在输入与输出端使用低 ESR 电解或固态电容配合旁路陶瓷,以改善瞬态响应与降低噪声。
  • 输出接近 1.5A 时注意 PCB 散热路径与器件结温检测,避免长期在极限条件下工作。
  • 结合过流和过热保护特性,可简化外部保护电路,但应验证系统在异常工况下的行为。

六、总结

LM29150RS-3.3 为一款结构简单、保护完善的 3.3V 固定稳压器,适用于需要可靠保护与中等电流输出的工业与嵌入式设计。合理的 PCB 散热与输入/输出去耦设计能最大化其性能与寿命。若需更详细的引脚定义与典型应用电路,请参考厂商完整资料或样片评估。

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
