MIC5365-3.3YD5-TR 产品概述

一、概述

MIC5365-3.3YD5-TR 为 MICROCHIP(美国微芯)推出的一款低功耗线性稳压器(LDO),固定输出3.3V,适用于对噪声、纹波抑制和待机功耗有较高要求的便携与物联网终端。器件支持使能控制,集成过流与过热保护,工作温度范围宽(-40℃ 至 +125℃@Tj),单通道输出并采用 TSOT-23-5 小封装,便于空间受限的应用。

二、主要参数

  • 输入电压上限:5.5V(工作电压)
  • 输出电压:3.3V(固定)
  • 输出电流:最大 150mA
  • 压差(Dropout):310mV @ 150mA
  • 静态电流(Iq):39µA(典型,低静态功耗)
  • 电源纹波抑制比(PSRR):70dB @ 1kHz
  • 输出噪声:约 200µVrms
  • 保护特性:过流保护、过热保护;带使能引脚
  • 输出极性:正极,单路输出
  • 工作温度:-40℃ ~ +125℃(结温范围)
  • 封装:TSOT-23-5

三、关键特性与优势

  • 低静态电流适合电池供电系统,可降低待机能耗;
  • 优异的PSRR 和低噪声性能,适合给模拟前端、RF 收发器或敏感传感器供电;
  • 低压差允许在较低输入余量下维持稳定输出,利于延长电池使用时间;
  • 带使能引脚便于系统电源管理与功耗控制;
  • 集成保护机制提高系统可靠性,简化外围保护电路设计。

四、典型应用场景

  • 便携式设备与可穿戴产品;
  • 电池供电的物联网节点、传感器模块;
  • 模拟/混合信号电路的基准/电源隔离;
  • 通信模块、低功耗微控制器供电。

五、封装与布局建议

TSOT-23-5 封装适合空间受限的 PCB 布局。为确保稳定与性能建议:输出端附近放置低 ESR 陶瓷电容(详见器件数据手册的推荐值与 ESR 范围),输入端添加去耦电容,缩短 VIN、GND、OUT 走线并使用完整的接地平面以优化热散与噪声抑制。使能管脚在不使用时应拉低以减少静态消耗。

六、热与保护注意事项

在接近最大输出电流时,应关注功耗与结温上升。器件内置过流与过热保护能在异常工况下自我保护,但在设计时仍需考虑散热路径与功率预算,以避免长期热应力。详细的容性负载稳定性、外围电容值及布局要求请参考 MICROCHIP 官方数据手册。

总体而言,MIC5365-3.3YD5-TR 是一款面向低功耗、低噪声应用的可靠固定输出 LDO,适合需在紧凑空间内实现稳定 3.3V 电源解决方案的设计场景。

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
