CJ6386A33M 是江苏长电/长晶(CJ)推出的一款固定输出线性低压差稳压器(LDO),输出电压为 3.3V,最大输出电流 250mA。器件支持高达 45V 的输入电压等级,具有超低静态电流和良好的电源抑制能力,适合对噪声、纹波和静态功耗有严格要求的应用场合。集成短路保护、过流保护与热关断功能,提高了系统可靠性并简化外围保护电路设计。器件采用 SOT-23-3L 小外形封装,方便空间受限的 PCB 设计与大批量装配。
优势要点:
典型应用:
热管理与功耗计算
稳定性与电容选择
抗浪涌与瞬态保护
PCB 布局建议
CJ6386A33M 采用 SOT-23-3L 小封装,适用于空间受限的商用电子设备。工作温度范围覆盖 -40℃ 至 +125℃,能够满足多数工业级温度要求。器件内部集成短路、过流与热关断三重保护,提高系统在异常工况下的容错能力。
CJ6386A33M 是一款面向高输入电压场合的低噪声、低静态电流固定 3.3V LDO,适合对电源净化与低功耗要求严格的应用。其高达 45V 的输入容忍度、70dB 的 PSRR 与 27µV rms 的低噪声表现,使其在音频、数据采集与工业控制等领域具有明显优势。但在高压差与高电流场合需重视功耗与散热问题,推荐结合前级降压或开关稳压器以减小热耗并保证长期可靠性。欲了解更详细的电气特性曲线、典型应用电路与封装尺寸,请参阅厂商数据手册或联系 CJ 技术支持。

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.
