XC6206-1.8V 产品概述

一、产品简介

XC6206-1.8V 是一款基于 CMOS 工艺并采用激光微调技术的高精度、低功耗三端正电压稳压器,适用于对电源噪声、纹波抑制和静态电流有严格要求的便携与低功耗系统。器件内部集成精密参考源、误差放大与驱动晶体管,能在极低压差下提供较大输出电流,适合以电池或单节电源为供电来源的应用。

二、主要规格(关键参数)

  • 输出极性:正极
  • 输出电压:固定 1.8V
  • 输出电流:最大 300mA
  • 工作电压(Vin 最大):8V
  • 压差(Dropout):约 280mV @ 100mA
  • 静态电流(Iq):典型 5µA(低静态功耗)
  • 电源纹波抑制比(PSRR):55dB @ 1kHz
  • 输出噪声:约 30µVrms
  • 保护功能:短路保护、过流保护
  • 工作温度范围:-40℃ ~ +85℃
  • 输出通道数:1 路固定输出
  • 封装:SOT-23

三、核心特点

  • 低压差:在中等负载下保持较低的压差,适合电池供电场景以延长工作时间。
  • 超低静态电流:待机电流仅为 µA 级,利于电池供电的长期待机设备。
  • 良好 PSRR 与低噪声:55dB@1kHz 与 30µVrms 噪声水准,适合对模拟/射频前端或精密传感器供电。
  • 内置保护电路:具短路与过流保护,提高系统可靠性,减少外部保护元件需求。
  • 小型封装:SOT-23 有利于空间受限的便携式产品设计。

四、典型应用

  • 移动终端与便携设备(便携式终端、蓝牙耳机、手持仪器)
  • 低功耗物联网节点、传感器前端与数据采集电路
  • 精密模拟电路、ADC/DAC 参考电源、射频前端供电
  • 电池管理、备份电源与消费电子产品

五、封装与引脚(SOT-23)

常见三引脚 SOT-23(从带标记面正对着看)引脚功能建议如下:
1 — GND(接地)
2 — VIN(输入)
3 — VOUT(输出)

  • 实际引脚与封装形式请以供应商数据手册为准。

六、外部元件与布局建议

  • 输入、输出侧建议各放置低 ESR 陶瓷电容(X5R/X7R):典型 1µF ~ 4.7µF,COUT 靠近 VOUT 引脚放置并有良好接地回流。
  • CIN 放置在 VIN 与 GND 之间,尽量靠近芯片输入引脚以抑制输入纹波与瞬态响应。
  • PCB 布局上,缩短 VIN→IC 与 VOUT→负载的走线,GND 使用固体地平面或短回流路径以降低噪声与热阻。
  • 高功率输出或持续大电流工作时注意封装散热,尽量增大铜箔面积用于热量扩散。

七、使用注意事项

  • 请确认系统最高输入电压不超过器件额定值(此处为 8V)。
  • 为保证稳压器稳定工作,应使用推荐范围内的输出电容及其 ESR。对于大容性负载或较长输出线,需评估稳定性与瞬态响应。
  • 虽具内部保护,但频繁在过流或短路条件下工作会影响可靠性,应在系统层面做好负载管理。
  • 如用于高精度或低噪声场合,可在输入端加滤波器、在输出端并联较大容量或引入 RC 滤波以进一步抑制噪声。

XC6206-1.8V(YONGYUTAI 永裕泰,SOT-23)以其低功耗、低噪声、良好 PSRR 与小体积特性,适合在对电源性能与能耗敏感的多种嵌入式与消费类电子应用中作为主稳压或局部稳压器使用。选型与设计时建议参照厂方详细数据手册以获取完整电气特性曲线与应用说明。

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
