XBL1117-3.3线性稳压器产品概述

一、产品核心定位

XBL1117-3.3是芯伯乐(XBLW)旗下1117系列的固定输出线性稳压器,针对「15V输入转3.3V/1A输出」的中功率稳压场景优化,具备工业级宽温可靠性与双重保护特性,适配SOT-223贴片封装,满足高密度PCB设计需求,广泛覆盖工业控制、车载电子等多领域应用。

二、关键性能参数明细

  1. 输入输出特性:输入电压范围覆盖4.6V~15V(最低输入为「输出3.3V+压差1.3V」),固定输出电压3.3V,正极输出,单通道设计;
  2. 负载能力:持续输出电流1A,满足多数中功率设备(如小型传感器、驱动模块)的供电需求;
  3. 功耗与纹波:静态电流(Iq)典型值4mA,1A负载下压差为1.3V,输出纹波抑制比(PSRR)约60dB@1kHz,有效降低电源噪声;
  4. 保护机制:内置短路保护(输出短路时自动限流关断)与过压保护(输入过压≥16V时切断输出,避免后端器件损坏);
  5. 温宽与封装:工作环境温度范围-40℃~+125℃(工业级标准),采用SOT-223贴片封装(尺寸约6.0×5.0×1.6mm),体积小巧,适配自动化贴装。

三、典型应用场景

XBL1117-3.3的宽温特性与保护功能,使其在多领域具备实用价值:

  1. 工业控制设备:PLC模块、传感器节点、电机驱动辅助电源,应对车间-20℃~+60℃的环境温度波动;
  2. 车载电子系统:车载显示屏、倒车雷达、小型车载通信模块,适配汽车启动时的9V~16V电压波动;
  3. 通信终端设备:小型基站、路由器、光纤收发器的辅助稳压电路,满足连续工作的稳定性需求;
  4. 医疗诊断仪器:便携式血糖仪、小型监护仪的低功率稳压单元,确保输出电压稳定可靠;
  5. 消费电子设备:部分中功率便携式设备(如移动投影仪、小型打印机)的电源转换模块。

四、产品优势与市场竞争力

对比同类1117系列产品,XBL1117-3.3具备以下差异化优势:

  1. 宽温可靠性:-40℃+125℃的工业级温宽,优于多数商用级产品(0℃70℃),可覆盖极端环境应用;
  2. 保护完善:短路+过压双重保护,减少设备因异常工况损坏的概率,降低售后成本;
  3. 封装适配性:SOT-223贴片封装体积小,适合高密度PCB设计,节省板级空间;
  4. 静态电流稳定:4mA静态电流在1A负载下保持恒定,不随负载变化大幅波动,提升轻载效率。

五、设计与使用注意事项

为确保产品性能稳定,应用时需注意以下要点:

  1. 电容配置:输入端并联10μF电解电容(或22μF陶瓷电容),输出端并联22μF陶瓷电容,抑制纹波与瞬态响应;
  2. 热管理:SOT-223封装散热能力有限,1A负载下需为各引脚预留≥10mm²铜箔面积,或加装小型散热片;
  3. 输入电压范围:严格控制输入电压在4.6V~15V之间,避免低于4.6V导致输出跌落,或高于15V触发过压保护;
  4. 布局建议:电容尽可能靠近稳压器引脚,减少走线阻抗,提升纹波抑制效果。

XBL1117-3.3以高可靠性、宽温适配性与紧凑封装,成为中功率稳压场景的实用选择,可满足多数工业与消费电子领域的电源转换需求。

Sourcing availability signal

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
