XTP2038-280AD1CT 低功耗低压差线性稳压器产品概述

XTP2038-280AD1CT是芯天下(XTX)推出的一款超小封装、低功耗型低压差线性稳压器(LDO),专为空间受限、电池供电及低功耗应用场景设计。产品集成过流、过热保护及使能控制功能,具备宽输入电压范围、极低静态电流等核心特性,可满足便携电子、物联网节点等领域的稳压需求。

一、产品定位与核心优势

该产品聚焦低功耗便携设备与工业级宽温应用,核心优势体现在以下四点:

  1. 超小封装集成:采用DFN1x1-4L封装,尺寸仅1.0mm×1.0mm×0.5mm,是同类产品中最小封装之一,可显著节省PCB空间;
  2. 极低静态电流:工作静态电流仅15μA,远低于传统LDO(通常50μA以上),大幅延长电池供电设备的续航时间;
  3. 低压差高效能:输出300mA时压差仅180mV,支持低输入电压场景(最小输入电压≈2.98V),适配电池放电末期的低电压工况;
  4. 多重保护集成:内置过流保护(OCP)、过热保护(OTP)及使能控制,提升系统可靠性,降低外围电路复杂度。

二、关键电气参数解析

XTP2038-280AD1CT的核心电气参数适配多场景需求,关键指标如下:

  • 输入/输出范围:输入电压范围为2.98V(VOUT+压差)~5.5V,输出电压固定为2.8V(精度典型值±1%),输出电流最大可达500mA;
  • 静态电流:正常工作时静态电流15μA,使能关断时静态电流<0.1μA,有效降低待机功耗;
  • 压差特性:在300mA负载电流下压差仅180mV,200mA负载时压差进一步降至120mV左右,确保低压输入下的稳定输出;
  • 温度范围:工作温度覆盖-40℃~+85℃,满足工业级环境及户外便携设备的宽温需求。

三、封装与引脚配置

产品采用DFN1x1-4L封装,引脚定义清晰,便于电路设计:

引脚编号 引脚名称 功能描述 1 VIN 直流输入电压端 2 GND 接地端 3 EN 使能控制端(高电平有效) 4 VOUT 稳压输出端

DFN封装具备优异的散热性能,PCB设计时可通过底部散热焊盘连接到地平面,进一步提升热耗散能力,适配500mA以内的负载功率。

四、典型应用场景

XTP2038-280AD1CT的特性使其广泛适用于以下场景:

  1. 可穿戴电子:智能手环、蓝牙耳机、智能手表等便携设备,低静态电流延长电池续航,小封装适配紧凑结构;
  2. 物联网(IoT)节点:环境传感器、低功耗无线模块(如BLE)等,宽温范围适配户外部署,使能控制支持远程休眠;
  3. 工业控制模块:小型PLC、传感器接口模块等,-40℃~+85℃宽温满足工业环境,多重保护提升可靠性;
  4. 消费电子配件:小型充电器、USB供电设备等,低压差适配低电压输入,稳定输出保障负载正常工作。

五、可靠性与保护特性

产品内置多重保护机制,提升系统稳定性:

  • 过流保护(OCP):当输出电流超过550mA(典型值)时,自动进入限流模式,防止负载短路或过载损坏芯片及负载;
  • 过热保护(OTP):结温超过150℃(典型值)时,芯片关断输出,温度降至120℃左右自动恢复,避免过热烧毁;
  • 使能控制:EN引脚高电平(>1.2V)开启输出,低电平(<0.4V)关断输出,关断时静态电流降至微安级以下,支持系统休眠管理。

六、应用设计注意事项

为确保产品稳定工作,设计时需注意以下要点:

  1. 输入/输出电容:建议在VIN与GND之间并联0.1μF陶瓷电容(靠近芯片),VOUT与GND之间并联1μF陶瓷电容(ESR<1Ω),抑制噪声及电压波动;
  2. 使能引脚:EN引脚需避免悬空,可直接接VIN(持续开启)或通过MCU GPIO控制(支持休眠);
  3. 散热设计:DFN封装底部散热焊盘需连接到PCB地平面,增加铜箔面积提升散热效率;
  4. 输入电压范围:最小输入电压需满足VOUT+压差(≈2.98V),实际应用建议输入电压≥3V,确保输出稳定。

XTP2038-280AD1CT凭借超小封装、低功耗、宽温特性及多重保护,成为便携设备与低功耗应用的理想稳压方案,可有效简化电路设计、提升系统可靠性。

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.
