ETA5055V180DS2F 是钰泰(ETA)面向低功耗与噪声敏感终端的固定输出线性稳压器,输出为正极 1.8V,单通道设计,封装为 SOT-23-5。器件集成过流保护、过热保护和使能功能,静态电流极低,适合电池供电和便携式系统。
器件采用 SOT-23-5 小外形封装,适合空间受限应用。常见引脚功能包括 VIN、VOUT、GND、EN(使能)及可能的备用/无连接引脚。具体引脚排列与封装机械图请参阅产品数据手册以确保 PCB 布局和焊接工艺正确。
在高负载情况下需注意功耗与封装散热:功耗近似为 (VIN − 1.8V) × IOUT。举例:若 VIN = 5.0V、IOUT = 500mA,则器件耗散约 1.6W;若 VIN = 3.3V、IOUT = 500mA,则约 0.75W。SOT-23-5 封装散热有限,建议通过加大铜箔面积、使用散热过孔或降低输入电压/输出电流来控制结温,确保不过热触发保护。
如需基于具体输入电压、负载情况的热耗计算、外部电容推荐或参考电路图,我可以进一步给出电路示例与 PCB 布局要点。

Product sourcing intelligence
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
Model text, package form, tray or reel details, and visual evidence are reviewed together before RFQ feedback.
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
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.
