MIC5528-3.3YMT-TR 产品概述

一、概述

MIC5528-3.3YMT-TR 是 Microchip 提供的一款高集成度线性低压差稳压器(LDO),为单路固定输出 3.3V 设计,最大输出电流 500mA。器件采用小型 TDFN-6-EP(1.2×1.2 mm)封装,适合对尺寸、噪声和电源纹波抑制有较高要求的便携与工业应用。

二、主要特性

  • 固定输出:3.3V,正极输出,单通道设计。
  • 工作电压:最高 5.5V 输入范围(典型系统工作条件下)。
  • 输出电流:最高 500mA 连续负载能力。
  • 优异抑制:PSRR 约 70 dB @100 Hz,适合敏感模拟/射频前端供电。
  • 低噪声:典型输出噪声 175 μVrms。
  • 保护与控制:带使能(EN)引脚、过热保护、过流保护和欠压锁定。
  • 工作温度范围:-40℃ 至 +125℃(结温 Tj)。
  • 封装小巧:TDFN-6-EP(1.2×1.2 mm),便于高密度系统集成。

三、性能与优势

MIC5528 在低噪声与高 PSRR 之间取得平衡,适合为 ADC、RF 前端、传感器和低噪放大器等敏感模块供电。内置保护电路提高系统可靠性;使能脚可实现电源管理策略和功耗控制。微小封装为移动设备、可穿戴和消费类电子节省 PCB 空间。

四、典型应用

  • 无线通信模块、射频接收前端供电
  • 精密模数转换(ADC)参考或前端供电
  • 便携式与电池供电设备电源管理
  • 工业控制与测量仪器低噪声电源

五、封装与布局建议

为保证稳定与热性能,建议输入侧和输出侧靠近器件放置低 ESR 陶瓷旁路电容(常见取值范围 1 μF ~ 10 μF,X5R/X7R)。器件底部的散热焊盘(EP)应接地并通过多填铜与热通孔扩散至内部/背面铜层,以降低结温并支持 500mA 输出时的热管理。布局时短而宽的电源走线、靠近器件放置旁路电容、EN 引脚走线避免噪声耦合,均有助于性能发挥。

六、选型与注意事项

在实际设计中应确认输入电压峰值和启动顺序符合器件的最大输入限制;评估在最大负载和高环境温度下的热裕度,必要时增加散热面积或考虑更低压降的电源拓扑。MIC5528-3.3YMT-TR 适合追求低噪声、高 PSRR 且对空间要求严格的系统,选型时请参考 Microchip 的完整数据手册与 PCB 布局参考范例以获得最佳性能。

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
