BLUE ROCKET 79D05 是一颗单通道固定输出的负电压线性稳压器(LDO),输出为 -5V,额定输出电流 1A。器件在常温下静态电流(Iq)为 8mA,典型噪声 100µV,电源纹波抑制比(PSRR)在 120Hz 时约为 60dB。压差(dropout)为 1.4V(在 1A 负载下),工作电压规范 20V,工作温度范围为 0℃~+125℃(Ta)。封装为 TO-252(DPAK),适合表面贴装与散热设计。
79D05 集成短路保护和过热保护两大防护机制:当输出发生短路或过流时进入限流状态以保护器件;当芯片温度过高时触发热关断以防止热失效。该类保护使器件在工业和移动负载变化场合具有较高的可靠性。
总结:79D05(TO-252)为一款面向工业与精密模拟应用的高 PSRR、低噪声、具备短路与热保护的 -5V/1A 线性稳压器。合理的外部滤波与 PCB 散热设计能显著提升稳定性与使用寿命。若需完整电气特性曲线与引脚定义,请参考官方 datasheet。

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.
