XTP2401-180ASA0CT — 40V、0.15A 固定输出 LDO 概述

一、概述

XTP2401-180ASA0CT 是芯天下(XTX)推出的一款高压低压差线性稳压器(LDO),固定输出 1.8V,最大输出电流可达 150mA。器件采用 SOT-89-3 小封装,工作电压上限可达 40V,适用于输入电压较高但对低压差与低静态电流有要求的各类电子终端与工业控制场景。器件集成热关断与短路保护,可靠性高,适合空间受限且需散热管理的方案。

二、主要特性

  • 输入电压范围:最高可达 40V(典型应用环境内)
  • 固定输出:1.8V,输出极性为正极
  • 最大输出电流:150mA
  • 压差(Dropout):650mV @ 150mA
  • 静态电流(Iq):典型 6µA(待机损耗低,适合电池供电)
  • 电源纹波抑制比(PSRR):45dB @ 1kHz(良好抑制中低频纹波)
  • 保护功能:热关断、短路保护
  • 工作温度:-40℃ 至 +85℃(Ta)
  • 封装:SOT-89-3(小型三引脚封装)

三、典型应用场景

  • 工业控制模块、传感器前端电源
  • 高压输入降压至 1.8V 的单片机或模拟电路供电
  • 电池供电设备(尤其需低静态电流以延长待机时间)
  • 测试测量仪器、便携设备的局部稳压
  • 需要高压输入容忍与保护的辅助电源场合

四、设计与布局建议

  • 输入端需配置合适的去耦电容:推荐在 Vin 与 GND 之间放置 1µF〜10µF 低 ESR 陶瓷电容,靠近器件输入引脚布局,以抑制入射噪声与瞬态尖峰。
  • 输出端同样建议放置 1µF〜10µF 低 ESR 输出电容,确保稳压环路稳定。若输出负载有较大瞬态,应适当增加电容容量或并联电解/钽电容以改善瞬态响应。
  • 在高电压输入场合,建议在输入处增加瞬态抑制器(TVS)或串联滤波器/熔断元件,用以应对浪涌与反向极性保护,避免超过器件最大承受电压。
  • SOT-89-3 封装散热能力有限,建议在 PCB 上为 GND 或板焊区域设计足够的铜面与过孔以提升散热。高功耗或高环境温度时需进行热仿真与输出电流限制,以避免触发热关断。
  • 引脚功能简单,典型引脚为:输入(Vin)、输出(Vout)、地(GND);布线应尽量缩短输出与地回路,减少寄生电阻/电感。

五、可靠性与注意事项

  • 器件内置短路保护与热关断机制,可在异常负载或过温状况下自动限制输出,有助于系统安全,但不应作为日常过载运行手段。设计时仍需避免长期在极限条件下工作。
  • 由于器件额定最高输入近 40V,若用于汽车或工业电源,应评估瞬态尖峰(如负载切换、大电流返回、雷击等)是否超出器件极限,必要时加装外部瞬态抑制或串联元件。
  • 对于需非常低噪声和高 PSRR 的前端电路,可结合外部滤波和良好接地设计进一步提升性能。

总结:XTP2401-180ASA0CT 在高输入耐受、低静态电流与适中输出电流条件下表现平衡,尤其适合需要从较高电压降至 1.8V 的应用场合。配合合理的输入瞬态防护与 PCB 散热设计,能在小体积封装中提供稳定、可靠的电源输出。若需详细电气特性曲线、封装图纸或典型应用电路,请参考芯天下官方数据手册或咨询芯天下技术支持。

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
