XTP2201-330ASACT 产品概述

一、产品简介

XTP2201-330ASACT 是芯天下(XTX)面向低功耗和电池供电设备设计的一款高性能线性稳压器(LDO)。器件固定输出 3.3V,最大输出电流可达 500mA,支持最高 18V 的输入工作电压,采用紧凑的 SOT89-3 封装,适合空间受限的消费电子、便携设备和工业控制应用。

二、核心参数

  • 输出类型:固定 3.3V,正极输出
  • 最大输出电流:500 mA
  • 最大输入电压(工作电压):18 V
  • 低压差(Dropout):135 mV @ 100 mA
  • 电源纹波抑制比(PSRR):76 dB @ 100 Hz
  • 静态电流(Iq):1.8 µA(超低功耗,适合待机场景)
  • 工作温度范围:-40 ℃ ~ +85 ℃(Ta)
  • 封装:SOT89-3,1 个输出通道

三、功能特性与保护机制

XTP2201-330ASACT 集成了多项实用功能与保护电路,提升系统可靠性与设计便利性:

  • 使能控制(EN):外部控制引脚用于开启/关闭输出,有利于系统省电策略与电源管理。
  • 短路保护与过流保护:自动限制异常电流,防止器件及负载损坏。
  • 输出放电:关断时快速把输出端电压放低,避免残余电压影响后续电路。
  • 热关断:温度过高时自动关断以保护芯片安全。

四、性能亮点

  • 超低静态电流(1.8 µA):非常适合电池供电或待机为主的应用场景,能显著降低静态功耗。
  • 高 PSRR(76 dB @ 100 Hz):在中低频纹波抑制表现优良,利于敏感模拟/射频/音频前端电源净化。
  • 低压差特性:在轻负载时仅 135 mV 的压差(100 mA),可在较小输入-输出差的条件下工作,从而延长电池寿命或简化电源设计。
  • 多重保护与输出放电:提升系统的安全性与可维护性。

五、封装与热管理

  • 封装形式:SOT89-3(紧凑型三引脚封装),适合空间受限的 PCB 布局。
  • 引脚功能:三引脚布局对应输入(VIN)、地(GND)与输出(VOUT),并包含使能/控制功能(EN)。
  • 散热建议:SOT89-3 的热阻相对较大,在接近 500 mA 输出或较高输入电压下,芯片功耗会增加,应通过合理的 PCB 铜箔(散热大面积地/散热垫)和短引线布局来改善散热,保证在规定温度范围内稳定工作。

六、典型应用

  • 便携式与电池供电设备(传感器节点、手持终端、可穿戴设备)
  • 工业控制与嵌入式系统(单板供电、MCU 电源)
  • 通信与网络设备(低噪声供电、射频前端供电)
  • 精密模拟电路与传感器接口(需高 PSRR 的场合)

七、使用建议与参考电路

  • 输入电压裕量:器件在 100 mA 时的压差仅 135 mV,但在更高输出电流下压差会增加,建议在不同负载工况下为 VIN 留出足够裕量(通常 VIN >= VOUT + 0.5 V 作为设计参考,具体应根据实际负载和电源条件评估)。
  • 输入/输出去耦:为保证稳压器稳定工作并抑制输入纹波,建议在靠近芯片的 VIN 端放置 1 µF10 µF 旁路电容(低 ESR 陶瓷电容),VOUT 端建议配置 4.7 µF10 µF 的低 ESR 输出电容并靠近芯片放置。
  • PCB 布局:VIN、VOUT 与 GND 的布线应尽量短且粗,GND 采用完整地平面以利散热与降低寄生阻抗。若有高电流路径,增加铜厚或增加散热铜箔面积。

八、订购信息与注意事项

  • 型号:XTP2201-330ASACT
  • 品牌:XTX(芯天下)
  • 封装:SOT89-3
  • 在选型与实际设计前,请参阅官方完整数据手册以获取引脚说明、EN 阈值、输出电容 ESR 范围、典型性能曲线及绝对最大额定值等详细参数。对于需要在高功率或高环境温度下持续 500 mA 输出的应用,务必做热仿真与实测验证,确保器件在安全工作区内运行。

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
