SGM2036-1.1YN5G/TR 产品概述

SGM2036-1.1YN5G/TR 是圣邦微(SGMICRO)推出的一款低压差线性稳压器(LDO),输出固定为 1.1V,采用 SOT-23-5 小尺寸封装,面向对尺寸、噪声和保护功能有较高要求的电源管理场景。该器件集成了使能控制、短路与过流保护、噪声旁路端子、输出放电以及热关断等多重保护与优化功能,适合便携式设备、传感器和低压数字核心供电等应用。

一、产品功能亮点

  • 使能控制(EN):通过外部逻辑控制器件启停,实现电源管理与功耗优化。
  • 短路保护与过流保护:内置限流和保护机制,在输出出现短路或过流工况时保护芯片及系统负载。
  • 噪声旁路端子(BYP/NC):提供降噪功能,外接旁路电容可有效降低输出噪声和提升瞬态响应(端子名称依具体封装或型号标记为 BYP/NC)。
  • 输出放电:在关断过程中快速放电输出节点,避免残余电压对后续电路造成干扰。
  • 热关断:当芯片内部温度超过安全阈值时自动关断,保证可靠性并防止热失控。
  • 小封装、易实现:SOT-23-5 封装利于空间受限的板级布局与自动贴片生产。

二、典型电气与使用特性(功能描述)

  • 稳压精度与稳定性:作为固定输出 1.1V 的 LDO,设计用于提供稳定、低噪声的参考电压输出,适合对电源噪声敏感的模拟与数模混合电路。
  • 低压差特性:器件具备低压差工作能力,可在输入与输出电压差较小时仍维持稳压,利于电池供电系统延长工作时间。
  • 低静态电流:适配电池供电应用时更低待机功耗(具体静态电流请参考产品数据手册)。
  • 输出电容兼容性:为了稳定性和低噪声,建议采用低 ESR 陶瓷电容作为输出旁路,常用范围为 1µF–10µF(根据系统要求和数据手册推荐值选择)。

三、典型应用场景

  • 便携式与电池供电设备:如智能手表、无线耳机、便携式传感终端等,需要低压差和低功耗的核心电源。
  • 模拟前端与传感器供电:为 ADC、传感器或精密放大器提供低噪声、稳定的参考电源。
  • 通信与射频模块:为敏感的收发前端或基带处理器提供洁净电源以保证信号完整性。
  • 工业控制与仪器:用于小型控制模块和测量设备的局部稳压,简化系统电源设计。

四、封装与订购信息

  • 封装类型:SOT-23-5,适合空间受限的 PCB 布局和自动化贴装工艺。
  • 封装标识:型号后缀 TR 表示卷带包装(Tape & Reel),适合量产与 SMT 工艺线使用。
  • 引脚功能:典型引脚包括输入(IN)、输出(OUT)、使能(EN)、旁路/噪声(BYP/NC)、地(GND)。具体引脚排列与功能请以官方数据手册为准。

五、设计建议与注意事项

  • 滤波与去耦:在输入端使用合适的去耦电容以抑制输入源阻抗造成的振荡;输出端推荐使用低 ESR 陶瓷电容以保证稳定与低噪声。
  • 使能控制:EN 引脚应按数据手册指定的电平驱动,避免在未定义区间长时间悬空以防不稳定状态。
  • BYP/旁路电容:若要求极低输出噪声或更快瞬态响应,可在噪声旁路端子与地之间添加合适的电容;不同容量会在噪声与瞬态性能之间权衡。
  • 热管理:尽管器件体积小,仍需考虑 PCB 散热路径与铜箔面积,避免长期高负载下温度过高触发热关断。
  • 保护与可靠性:在可能出现短路或过流事件的应用中,器件内置保护能提高系统鲁棒性,但仍建议在电路设计层面加入必要的外部保护与滤波。

六、总结

SGM2036-1.1YN5G/TR 是一款集成多项保护功能与降噪能力的 1.1V 固定输出 LDO,凭借 SOT-23-5 小封装与使能、输出放电、短路/过流保护、热关断等特性,非常适合便携和对电源质量有严格要求的应用场合。在实际设计中,请参考官方数据手册以确认电气参数、引脚定义和典型应用电路,按照手册的外部元件建议进行布局和旁路电容选择,以获得最佳性能与可靠性。

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
