SGM2203-3.3YN5G/TR 产品概述

一、产品简介

SGM2203-3.3YN5G/TR 是 SGMICRO(圣邦微)推出的一款低功耗、低噪声固定输出线性稳压器(LDO),输出电压为 3.3V,最大输出电流 150mA。器件采用 SOT-23-5 小尺寸封装,工作温度范围 -40℃ 至 +85℃(Ta),适合对尺寸、功耗与纹波抑制有较高要求的便携式与嵌入式应用。

二、主要特点

  • 固定输出:3.3V 正极输出,单通道设计,使用方便。
  • 宽输入电压范围:器件工作电压上限可达 36V(详见数据手册),便于在高压源或多节电池供电场合使用。
  • 低静态电流:静态工作电流 Iq 为 4.2µA,有利于延长电池供电系统的待机时间。
  • 低压差:压差(Dropout)典型值 1.85V(在 150mA 负载时),适用于中等电流负载。
  • 高 PSRR:在 1kHz 时电源纹波抑制比 PSRR 可达 55dB,有利于降噪与提高系统模拟性能。
  • 保护功能:集成过流保护(OCP)和过热保护(OTP),增强系统可靠性。
  • 小封装:SOT-23-5 便于空间受限的 PCB 布局与成本控制。

三、电气参数要点

  • 输出电压:3.3V(固定)
  • 最大输出电流:150mA
  • 压降:1.85V @ 150mA
  • 静态电流:4.2µA(典型)
  • PSRR:55dB @ 1kHz
  • 保护:过流保护、过热保护
  • 工作温度:-40℃ ~ +85℃(Ta)
  • 封装:SOT-23-5

四、典型应用场景

  • 便携式仪表与低功耗手持设备
  • 电池供电的物联网节点、传感器模块与无线终端
  • 工业控制与数据采集系统中的数字/模拟电源
  • 需要良好纹波抑制的 ADC/DAC、RF 前端电源供给场合

五、布局与外围元件建议

  • 输入端与输出端应靠近器件放置去耦电容,以降低寄生感抗与环路不稳定风险。建议采用低 ESR 的陶瓷电容(典型范围 1µF ~ 10µF,具体数值以数据手册推荐为准)。
  • 在高电压输入应用中,注意输入电容的额定电压与耐压裕量。
  • PCB 布局时将 GND 引脚短接到完整地平面,热流通过铜箔散热,SOT-23-5 封装在高功耗或连续大电流条件下需注意热阻与散热设计。
  • 若器件含旁路或使能引脚,应按数据手册配置相应滤波或拉高/拉低电阻以保证最佳噪声和启动性能。

六、封装、可靠性与选型注意

SOT-23-5 小型封装便于自动化贴装与成本控制,适合大多数商用与工业级产品。选型时应关注实际负载电流、输入电压区间、热环境与启动/短路行为,必要时参考完整数据手册中的温升曲线、最大功耗与外置元件推荐。若系统对超低压差或更高电流有需求,可考虑并行级或替代型号。

总结:SGM2203-3.3YN5G/TR 以其低静态电流、良好 PSRR 与完整保护功能,适合对待机能耗与电源质量有严格要求的小型应用,是便携设备与嵌入式电源设计的实用选择。请在最终设计前查阅并遵循制造商的完整数据手册与应用笔记。

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
