WL2836D30-4/TR 产品概述
一、产品简介
WL2836D30-4/TR 是 WILLSEMI（韦尔）推出的一款固定输出线性稳压器，输出电压为 3.0V，面向对低噪声、高PSRR 和电池供电友好型设计的便携与嵌入式设备。器件采用紧凑的 DFN-4-EP（1×1mm）封装，适合高密度 PCB 布局。
二、主要参数
- 输出类型：固定（3.0V）
- 最大工作电压：5.5V（输入端建议不超过此值）
- 最大输出电流：300mA
- 压差（Dropout）：185mV @ 300mA（低压差特性，有利于提高效率）
- 静态电流（Iq）：50µA（适合电池供电设备的低待机损耗）
- PSRR：78dB @ 1kHz（对电源纹波有很强的抑制能力）
- 工作温度：-40℃ ~ +85℃（Ta）
- 输出极性：正极，单通道输出
三、性能与保护
WL2836D30-4/TR 在设计中集成了过热保护与短路保护，能够在异常负载或过热条件下自动限流或关断，从而提高系统可靠性。高 PSRR 对开关电源噪声抑制显著，适合对模拟或射频前端噪声要求高的应用。低静态电流和低压差使其在电池寿命与能效之间取得良好平衡。
四、封装与热管理
DFN-4-EP（1×1mm）带有中心散热焊盘，可通过 PCB 热负载过孔与大铜箔进行散热。由于线性稳压器的功耗与输入输出压差成正比（Pd = (Vin − Vout)×Iout），在 Vin 较高且输出接近最大电流时，器件功耗可能较大，需在 PCB 设计中预留足够的散热面积并采用多层铜箔或过孔导热，以防止热关断或降低输出能力。
五、应用场景与设计建议
适用场景包括：便携式电子、物联网终端、传感器供电、MCU/模拟电路的 3.0V 低噪声电源等。设计建议：
- 在输入端及输出端放置近旁的低 ESR 陶瓷旁路电容（例如 1µF～10µF，具体按数据手册确认），以保证稳定性与瞬态响应；
- 将散热焊盘用焊盘填充并连接到多层大面积铜层，必要时使用过孔增强热传导；
- 布局时将输入/输出走线尽可能短，地线采用单点或平面化处理以降低噪声耦合；
- 在高功耗工况下通过降低输入电压或限制输出电流来控制器件发热。
六、订购信息与小结
型号：WL2836D30-4/TR，品牌：WILLSEMI（韦尔），封装：DFN-4-EP（1×1），后缀 /TR 表示卷盘（Tape & Reel）包装。WL2836D30-4/TR 以其低压差、低静态电流与高 PSRR 的组合，适合对噪声敏感且有能耗约束的 3.0V 电源设计。建议在具体方案中参考器件完整数据手册以获取管脚定义、外部元件建议及电气极限值。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
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.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
