CJ6388B50M 是江苏长电(CJ/长晶)推出的一款高输入耐压线性稳压器(LDO),提供固定 5.0V 输出,单通道输出,适用于高压输入场景的低噪声稳压需求。器件工作温度范围宽(-40℃ ~ +125℃,以结温 Tj 计),静态电流极低,仅 3μA,具有短路保护、过流保护、热关断和使能控制等实用保护与控制功能,封装为 SOT-23-5L,便于小尺寸 PCB 设计与批量贴装。
备注:资料中对最大输出电流存在不一致描述(有 150mA 与 250mA 两种说法),请以厂家最新数据手册为准。
SOT-23-5L 封装利于小体积设计与自动贴片生产。焊接工艺遵循常规无铅回流规范,焊盘与热散设计应参考封装推荐图与热阻参数,以优化热性能与可靠性。
总结:CJ6388B50M 以高输入耐压、低静态电流及良好 PSRR 为特点,适合在高压输入且对噪声或功耗有特殊要求的应用场景。最终选型与布局请结合厂家数据手册进行详细验证。

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.
