TMI6050-33 是拓尔微(TMI)推出的一款固定输出、正极性线性稳压器,输出电压为 3.3V,单通道设计,封装为 SOT-23-5。器件集成了短路保护、过流保护、过热保护及使能(EN)功能,适用于对可靠性和体积有要求的便携与嵌入式电源系统。
TMI6050-33 在典型工作点具备稳定的 3.3V 输出,静态电流仅 75µA,满足低功耗待机需求。600mA 的输出能力配合 600mV 的压差表明在满载时输入电压至少需高于约 3.9V(建议 VIN ≥ VOUT + 0.6V 以上以保证裕量)。PSRR 60dB@1kHz 对噪声敏感的模拟或射频电路尤为有利。
SOT-23-5 小封装便于空间受限的应用,但热阻相对较大。大电流工作时需在 PCB 上通过铜箔铺铜和散热过孔来提升散热能力,避免因结温上升触发热关断。合理的走线和地铜平面可显著改善功率耗散。
适合的应用场景包括:
型号:TMI6050-33,品牌:拓尔微(TMI),封装:SOT-23-5。选型时确认系统最大输入电压、最小输入裕量以及持续输出电流需求,评估 PCB 热管理能力,并参考厂方完整 datasheet 以获取引脚定义、典型应用电路和详细电气特性曲线。

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.
