SGM2019-2.5YC5G/TR 产品概述

一、产品简介

SGM2019-2.5YC5G/TR 是圣邦微(SGMICRO)推出的一款低压差线性稳压器(LDO),为单路固定输出的正极性稳压器,输出电压为 2.5V,适用于对噪声、稳定性和电源抑制有较高要求的小型化供电方案。器件采用 SC-70-5 小封装,适合便携与空间受限的电路板设计。

二、主要性能参数

  • 工作电压(最大输入):5.5V
  • 输出电压:2.5V(固定)
  • 最大输出电流:250mA
  • 压差(Dropout):400mV @ 300mA
  • 静态电流(Iq):200µA
  • 输出噪声:30µVrms
  • 电源纹波抑制比(PSRR):74dB @ 1kHz
  • 工作温度范围:-40℃ 至 +85℃
  • 输出通道数:1

三、功能与保护特性

  • 使能控制(Enable):可通过外部引脚实现开/关控制,降低关断功耗。
  • 短路保护:内置限流与保护逻辑,发生短路时限制输出电流,保护器件与负载。
  • 可调限流:支持通过外部元件对限流阈值进行设置(具体方法请参考器件手册)。
  • 热关断:当芯片温度超限时自动关闭输出,防止过热损坏。

四、典型应用场景

适用于电池供电设备和低功耗系统,包括便携终端、传感模块、物联网节点、数模混合电路的参考电源、摄像模块和工业控制电路等,对噪声和 PSRR 有要求的模拟/射频前端尤其受益。

五、封装与使用建议

  • 封装:SC-70-5,小型化封装便于空间受限设计。
  • 布局建议:靠近输入端放置旁路电容,输出端配合低 ESR 陶瓷电容以保证稳定性与低噪声;尽量缩短电源和地回路以提升 PSRR 表现。
  • 散热考虑:在高输出电流或大压差工况下注意器件自热,必要时在 PCB 上扩大散热铜箔。

SGM2019-2.5YC5G/TR 以其低噪声、高 PSRR、小体积与完善的保护功能,为对电源品质有要求的应用提供了可靠且经济的解决方案。欲了解详细引脚定义、典型电路和限流设定方式,请参阅圣邦微正式数据手册。

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
