HRT9013-33GB 产品概述

一、产品简介

HRT9013-33GB 是华轩阳电子(HXY MOSFET)推出的一款固定输出 3.3V 低压差线性稳压器(LDO),采用 SOT-23-5L 小封装,面向对功耗、噪声与电源抑制有较高要求的便携与嵌入式应用。器件设计注重低静态电流与良好的瞬态响应,适合电池供电或对待机功耗敏感的系统。

二、主要性能指标

  • 输出电压:3.3V(固定)
  • 最大输出电流:500mA
  • 工作电压:7V(推荐输入条件)
  • 压降(Dropout):100mV @ 100mA(低压差特性)
  • 静态电流(Iq):75µA(低静态功耗)
  • 噪声:50µVrms(低输出噪声)
  • 电源纹波抑制(PSRR):75dB @ 1kHz(优秀的纹波抑制)
  • 保护功能:过流保护、短路保护
  • 工作温度:-40°C ~ +85°C(Ta)
  • 输出极性:正极;通道数:1

三、保护与可靠性

HRT9013-33GB 内置过流与短路保护机制,可在异常负载条件下限制输出电流,避免器件与负载损坏。设计时仍建议考虑热限流与功耗管理:当输入为7V、输出3.3V且满载500mA时,器件功耗可达约1.85W,应通过 PCB 散热设计与功率预算进行恰当热管理,以保证长期可靠性与温升控制。

四、封装与热设计

SOT-23-5L 小封装适合空间受限应用,但导热能力有限。建议在 PCB 上预留宽铜箔散热区域(热沉铜)并连接 GND 平面以降低结壳温度;必要时采用多层板和过孔导热方式。典型应用中应按最大结温限制对输出电流进行温度折减。

五、典型应用场景

  • 物联网终端、传感器节点、电池供电设备
  • MCU 与外围电源(3.3V 数字电路)
  • 射频/模拟前端电源(得益于高 PSRR 与低噪声)
  • 可穿戴设备、手持仪表、消费类电子

六、应用建议与 PCB 布局

  • 输入端建议并联至少 1µF10µF 低ESR 陶瓷电容以抑制输入纹波;输出端推荐 4.7µF10µF 低ESR 陶瓷电容以保证稳压器稳定与低噪声输出。
  • 尽量将输入/输出电容靠近器件引脚放置,缩短电流回路、减小寄生阻抗。
  • 共地布线,使用实心地平面,避免敏感模拟或 RF 节点与大电流回路交叉。
  • 在高功耗或连续满载场景下,做必要的热仿真与实测,必要时限制最大输出或改用更大封装/外部散热。

七、使用注意事项

  • 虽然在 100mA 时压降仅 100mV,但在更高电流下压降会增加,设计时应预估负载电流与输入电压范围。
  • 对于对噪声和纹波极敏感的系统,可配合后级滤波或添加差分/共模滤波措施进一步改善电源质量。
  • 在极端环境或高温条件下,请根据器件数据手册进行功率与热平衡评估并做必要降额使用。

HRT9013-33GB 在小封装下提供了低静态电流、低噪声与良好 PSRR 的 3.3V 稳压输出,是对空间、功耗与电源质量有综合要求应用的合适选择。若需器件详细典型电路图与 PCB 参考布局,请参照厂家规格书或联系供应商获取完整资料。

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
