SGM2225-ADJXS8G/TR 产品概述

SGM2225-ADJXS8G/TR 是圣邦微(SGMICRO)推出的一款高性能可调线性稳压器,适用于对噪声、纹波抑制和低功耗有严格要求的便携与工业电子设备。器件以 SOIC-8 封装提供单路正向可调输出,覆盖从 1.8V 到 15V 的输出电压范围,在高达 36V 的工作电压下可稳定输出最多 800mA 电流,具有优秀的电源纹波抑制和保护功能。

① 主要规格与性能亮点

  • 输出类型:可调(1.8V ~ 15V)
  • 最大输入电压:36V
  • 最大输出电流:800mA
  • 压降(Dropout):450mV @ 800mA
  • 静态电流(Iq):典型 80μA(低静态功耗)
  • PSRR:75dB @ 1kHz(优秀的纹波抑制能力)
  • 输出极性:正向单路输出
  • 保护特性:短路保护与热关断
  • 工作温度范围:-40℃ ~ +125℃(Ta)
  • 封装:SOIC-8

② 功能特性与优势

SGM2225 提供低压差并在大电流条件下仍能保持较小压降,适合需要较高负载能力且电源头寸有限的场合。75dB@1kHz 的高 PSRR 对音频、传感器供电或高精度模数电路尤为重要,能有效抑制开关电源或外部干扰引起的纹波。典型 80μA 的静态电流在待机或轻载状态下可显著降低系统功耗。内置短路和热关断保护提升系统可靠性,简化外部保护电路设计。

③ 典型应用场景

  • 便携式设备的主/从电源管理
  • 工业控制与自动化模块的模拟、参考供电
  • 音频前端与传感器供电,需低噪声电源场合
  • 通信设备与车载电子(在符合系统温度与电压规范下)

④ 设计建议与注意事项

  • 输出稳定性:建议按圣邦微参考设计选择输入/输出电容。常采用低 ESR 电容(陶瓷或钽电容组合)以保证环路稳定与瞬态响应。
  • 热管理:SOIC-8 封装的散热能力有限,高达 800mA 时需关注 PCB 散热设计,可通过增加铜箔面积、热过孔或散热片降低结温,避免触发热关断。
  • 可调电阻网络:在设置输出电压时,使用高精度分压电阻以保证输出准确度,并考虑调整引脚的噪声抑制与滤波。
  • 保护与启动:短路保护与热关断提供基本防护,但建议在系统层面配合过流检测或电源序列管理以提高可靠性。

SGM2225-ADJXS8G/TR 以其低静态电流、低压差和优异的纹波抑制性能,适合对电源品质和效率都有较高要求的系统设计。有关详细引脚定义、典型电路和 PCB 布局建议,请参照圣邦微官方资料与参考设计。

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
