L7805CDTR(芯伯乐XBLW)线性稳压器产品概述

一、产品定位与核心特性

L7805CDTR是芯伯乐(XBLW)推出的固定输出线性稳压器,专为中等电流需求的电源转换场景设计,兼容传统7805系列的功能逻辑,同时在噪声抑制、温度适应性等方面做了针对性优化。其核心特性可总结为:

  • 固定5V精准输出,无需外部调整元件;
  • 1.5A最大负载能力,覆盖多数中小功率应用;
  • 80dB@120Hz高电源纹波抑制比(PSRR);
  • 40μV低输出噪声,适合对噪声敏感的模拟电路;
  • 内置短路保护+过热保护双重防护;
  • -20℃~+125℃宽结温范围,满足工业级环境需求。

二、关键电气参数详解

1. 输出与输入特性

输出电压为固定5V(精度符合工业级标准),最大输出电流1.5A,可稳定驱动微控制器、传感器、小功率LED等负载。输入电压上限为35V,结合2V@500mA的压差,实际输入电压建议维持在7V~35V(5V输出+2V压差=7V),确保输出电压不随输入波动而下降。

2. 纹波与噪声抑制

  • 电源纹波抑制比(PSRR)达80dB@120Hz,可有效衰减市电整流后的低频纹波(100/120Hz),减少电源噪声对后级电路的干扰;
  • 输出噪声仅40μV(典型值),远低于普通线性稳压器,适合音频电路、医疗传感器等对噪声敏感的场景。

3. 静态电流与压差

  • 静态电流(Iq)为6mA,在同类产品中处于合理水平,既保证稳压器自身稳定,又不会过度消耗输入功率;
  • 压差为2V@500mA,说明在500mA负载下,输入电压只需比输出高2V即可稳定工作,降低了对输入电源的要求。

4. 保护功能

  • 短路保护:输出短路时自动限制电流(约2A),避免器件过流损坏;
  • 过热保护:结温超过阈值(约150℃)时关断输出,温度降至100℃左右自动恢复,防止高温烧毁。

5. 温度适应性

工作结温范围为-20℃~+125℃,覆盖工业级环境的温度波动(如户外设备、车间控制柜),无需额外温度补偿电路。

三、封装与可靠性设计

L7805CDTR采用TO-263贴片封装,体积小巧(约6.5mm×8.5mm),适合高密度PCB布局;封装自带散热焊盘,可通过PCB铜箔有效导出热量,降低结温。该封装符合工业级可靠性标准,抗振动、抗冲击能力强,适合车载、工业控制等振动环境。

四、典型应用场景

  1. 工业控制:PLC辅助电源、传感器模块、小型电机驱动电路;
  2. 消费电子:机顶盒、路由器、智能音箱的核心芯片供电;
  3. 汽车电子:车载显示屏、倒车雷达、行车记录仪辅助电源;
  4. 通信设备:基站小模块(射频前端、光模块)电源;
  5. 医疗设备:小型监护仪、血糖仪的传感器供电。

五、使用注意事项

  1. 输入电压:避免低于7V(压差不足)或超过35V(过压损坏);
  2. 散热设计:PCB需预留≥10mm²散热铜箔,1.5A负载时建议加装小型散热片;
  3. 电容配置:输出端并联10μF电解电容+0.1μF陶瓷电容,输入端并联1μF陶瓷电容;
  4. 保护恢复:短路排除后自动恢复,过热后需降温至100℃左右恢复;
  5. 焊接要求:焊接温度≤260℃(回流焊),时间≤10秒,注意ESD防护。

L7805CDTR凭借稳定的输出性能、完善的防护功能和宽环境适应性,成为传统7805系列的高性价比替代方案,适用于多领域的电源设计需求。

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
