XTP2401-500ASA0CT 产品概述

一、产品简介

XTP2401-500ASA0CT 是芯天下(XTX)推出的一款高压、低功耗线性稳压器(LDO),输入电压最高可达40V,固定输出5.0V,最大输出电流150mA。器件采用SOT-89-3 封装,设计用于在宽输入电压范围内为模拟和数字负载提供稳健、低噪声的 5V 电源,可作为常用 78L05 的直接替代品,且在压差、静态电流与抑制电源纹波等方面具有明显优势。

二、主要性能参数

  • 输出极性:正极
  • 输入电压上限:40V
  • 输出电压:5.0V(固定)
  • 最大输出电流:150mA
  • 压差(Dropout):650mV @ 150mA(低压差设计,有利于高效率与低发热)
  • 静态电流 Iq:6µA(超低静态电流,适合电池供电与待机系统)
  • 电源纹波抑制比(PSRR):45dB @ 1kHz(良好的噪声抑制能力)
  • 工作温度范围:-40°C ~ +85°C

三、保护与可靠性设计

XTP2401-500ASA0CT 集成多重保护机制,提升系统可靠性:

  • 过流保护(OCP):在异常负载或短路时限制输出电流,防止器件损坏。
  • 短路保护(SCP):在持续短路情况下提供保护并允许自动恢复。
  • 热关断(Thermal Shutdown):发生过热时自动关断,冷却后自动恢复,防止热失控。

四、封装与管脚

  • 封装:SOT-89-3,适合空间受限但需要比SOT-23更好散热的应用场合。
  • 物理替换:与常见的 78L05 电路兼容,能在多数电路中直接替换,且具有更优的静态电流与压差表现。

五、典型应用场景

  • 电池供电设备与便携式仪器(超低静态电流降低待机消耗)
  • 工业控制与通讯设备(宽输入电压支持 12V / 24V / 36V 等系统)
  • 模拟前端与传感器供电(较高 PSRR 有利于降低系统噪声)
  • 替代 78L05 的升级改造,缩小尺寸并改善效率与噪声性能

六、使用建议与注意事项

  • 外部电容:建议在输入端并靠近芯片放置 0.1µF 陶瓷旁路电容;输出端建议 1µF~10µF 低ESR 电容以保证稳态与瞬态稳定性(具体值请参考应用说明书)。
  • 散热考量:线性稳压器的功耗与输入—输出压差及负载电流相关,Pd = (Vin − Vout) × Iout。SOT-89 封装散热有限,长时间在高压差高电流条件下工作需注意热量管理或在前端采用降压预处理。
  • 汽车应用:器件输入耐压为40V,若用于汽车或存在高压瞬态的环境,应增加浪涌抑制与瞬态抑制元件以保证可靠性。

七、选型优势

XTP2401-500ASA0CT 在保持兼容 78L05 的同时,提供更低的静态电流、更小的压差和更好的纹波抑制,适合对功耗与干扰敏感的现代电子系统。SOT-89 封装在尺寸与散热之间取得平衡,是替代传统 TO-92/TO-126 等封装的理想选择。

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
