WL2808E12-5/TR 产品概述

一、产品简介

WL2808E12-5/TR 是 WILLSEMI(韦尔)推出的一款固定输出线性稳压器,输出电压 1.2V,适用于对噪声、纹波和稳定性有较高要求的小功率供电场合。器件采用 SOT-23-5L 封装,单通道正极输出,内置保护功能,适合移动设备、嵌入式系统和各类数字核心电源场景。

二、主要性能指标

  • 输出类型:固定(1.2V)
  • 工作电压(Vin):最高 5.5V(详见数据手册绝对最大额定)
  • 最大工作电流:200mA
  • 压差(Dropout):170mV @ 200mA
  • 静态电流(Iq):典型 30µA(低静态功耗,适合电池供电)
  • 电源纹波抑制比(PSRR):75dB @ 217Hz
  • 输出噪声:100µVrms
  • 工作温度范围:-40℃ ~ +85℃(Ta)
  • 保护与控制:短路保护、过流保护、使能(EN)脚
  • 封装:SOT-23-5L,单通道正极输出

三、功能特点与优势

  • 低压差:在满载 200mA 时仅 170mV 的压差,有利于低差压供电设计,节省输入电压裕量。
  • 低静态电流:30µA 的典型静态电流,有利于延长电池寿命。
  • 优良的抑制与低噪声:75dB 的 PSRR(217Hz)与 100µVrms 的低噪声输出,适合敏感模拟/数字混合电路的核心电源。
  • 集成保护:内置短路与过流保护,提升系统可靠性;带使能引脚,便于系统电源管理。

四、典型应用

  • 数字芯片核心电源(MCU/MPU/FPGA/ASIC 核心 1.2V)
  • 无线通信模组、电源管理模块
  • 电池供电与便携式设备的低压轨供电
  • 精密模拟前端与传感器供电

五、设计建议与注意事项

  • 输入/输出电容:建议在 VIN 与 VOUT 端分别放置低 ESR 陶瓷电容(如 1µF~10µF,X5R/X7R),并靠近器件引脚布局以保证稳定性与瞬态响应。
  • 热设计:在最大输入电压(近 5.5V)和满载条件下,器件功耗为 (Vin - 1.2V)×Iout,需注意 SOT-23-5L 的散热限制,必要时加大铜箔面积或采用散热垫/热孔。
  • 使能与启动:使能脚用于外部开关控制,具体电平极性及上电序列请参阅器件数据手册以避免异常工作。
  • 布局:建议器件底部与地平面连接良好,减少噪声耦合并优化热扩散;输入滤波与负载电流回路应尽量短且粗。

六、封装与订购信息

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
