TLE42744DV50 是英飞凌(Infineon)面向高电压输入场景推出的一款固定输出线性稳压器(LDO),提供稳定的 5.0V 正向输出,最大输出电流可达 400mA。器件集成多重保护功能(过压、过流、短路与过热保护),适合需要高可靠性与低噪声电源的工业与汽车类应用。
器件内置热关断,能在过热时保护器件与系统。实际使用时需对结温进行评估并在高温环境下做额定电流降额设计,确保长期可靠性。工作结温上限为 150℃,系统应保证在此范围内运行并留有安全裕度。
TLE42744DV50 将高输入耐受性、低静态电流与良好纹波抑制结合在小型 DPAK 封装中,适合对可靠性和噪声有较高要求的工业与车载电源应用。设计时重点关注输入裕量与散热管理,并按厂商建议选择合适的输出电容与 PCB 布局,可获得稳定、低噪的 5V 电源输出。若需详细电气特性曲线及典型应用电路,建议参考英飞凌器件数据手册。

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.
