CJ78D05 为单路固定输出线性稳压器,主要参数如下:输出电压 5V;最大工作电压 35V;最大输出电流 1A;静态电流(Iq)约 3.5mA;压差(dropout)2V @ 1A;电源纹波抑制比 PSRR 68dB(120Hz);输出噪声约 10μV(典型值);工作结温范围 -25℃ ~ +125℃(Tj);封装为 TO-252-2 (DPAK)。输出为正极,单通道设计,适合需稳压5V且电流不超过1A的应用。
在选型阶段,应综合考虑输入电压范围、最大负载电流及散热条件。若系统输入电压长期远高于5V且负载接近1A,建议使用开关降压后接 LDO 做后端滤波以降低总体功耗并利用 LDO 的低噪特性。长期在高温或高功率耗散条件下工作时,需按热阻与结温极限进行可靠性评估并预留安全裕度。
如需器件详细电气特性曲线、引脚图和热阻数据,请提供或参考 CJ 的完整数据手册以获得精确设计参数。

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.
