SGM2036S-1.8XN5G/TR 产品概述

一、产品简介

SGM2036S-1.8XN5G/TR 是圣邦微(SGMICRO)推出的一款固定输出、正极单通道低压差线性稳压器(LDO),输出电压为1.8V,适用于对噪声、功耗和纹波抑制有较高要求的便携与工业电子设备。器件封装为SOT-23-5,体积小,便于板级空间受限场合使用。

二、主要参数

  • 输出类型:固定(1.8V)
  • 最大工作电压:5.5V
  • 最大输出电流:300mA
  • 压差(Dropout):420mV @ 300mA
  • 静态电流(Iq):20µA(低静态功耗,适合电池供电)
  • 噪声:30µVrms(低噪声)
  • PSRR:75dB @ 1kHz(优良的电源纹波抑制)
  • 保护功能:短路保护、热关断
  • 工作温度:-40℃ ~ +85℃
  • 封装:SOT-23-5

三、关键特性与性能亮点

  • 高PSRR(75dB@1kHz)能有效抑制输入端纹波与开关电源噪声,对于敏感的模拟前端、ADC 或射频模块尤为重要。
  • 低噪声(30µVrms)保证对精密参考电压和低噪声模拟电路的供电质量。
  • 低静态电流(20µA)极大延长电池供电系统的待机时间,适合物联网节点和便携设备。
  • 较小的压差(420mV@300mA)降低在低压差运行时的功耗,使器件在较低输入电压下仍能稳定输出1.8V。
  • 内置短路保护与热关断提高系统可靠性,免去额外保护电路设计。

四、应用场景

  • 电池供电的便携设备、穿戴式终端与物联网节点
  • 微控制器、传感器和射频模块的电源管理
  • 精密模拟电路、数据采集系统和低噪声前端电源
  • 工业控制与通信终端中对稳定1.8V电源的需求场合

五、封装与典型注意事项

SOT-23-5 小封装适合空间受限的应用。设计时应关注器件的散热与布局:尽量增加输入/输出去耦电容的靠近走线,遵循厂商数据手册对电容类型与等效串联电阻(ESR)的推荐值,以确保稳定性与最佳瞬态响应。计算功耗时按 P = (Vin - Vout) × Iout 估算,若输入电压较高且接近满载电流时需关注芯片温升与PCB散热设计。

六、选型建议

若系统需要1.8V、最高300mA 输出,且对噪声与纹波抑制有较高要求,同时又关注待机功耗与成本,SGM2036S-1.8XN5G/TR 是一个均衡的选择。最终采用前请参阅圣邦微完整数据手册,确认外部电容规范、最大绝对额定值及热特性,以保证设计可靠并满足应用需求。

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
