SSP7615-12M5R 是上海矽朋(Siproin)推出的一款高精度、低噪声、高速 CMOS 线性稳压器(LDO),输出为固定正极 1.2V,单通道设计,适合对噪声、精度和待机功耗有严格要求的便携式电子设备。器件具备极低静态电流和低压差特性,即使在输入输出电压差较小时也能提供较大的输出电流,具有良好的性价比与布局灵活性。
SSP7615-12M5R 在中高电流工作点仍保持较低压差(LDROP),200mA 时典型压差为 400mV,满足电池供电或多轨电源系统中靠近输入电压的低压差稳压需求。60dB@1kHz 的 PSRR 表明其能有效抑制电源纹波和开关噪声,适用于对模拟、RF 或 ADC/DAC 前端供电的噪声敏感场合。450nA 的超低静态电流非常适合电池待机场景,有利于延长设备续航。
器件集成了常用保护与控制功能:
标准 SOT-23-5 封装适合通用 SMT 贴片组装,另外还提供 SOT-23-3 与超小型 DFN1×1-4 可选,便于在空间受限的移动设备及模块化电源板上采用。器件为无铅无卤工艺,满足现代环保与可靠性要求。
为保证稳压器的稳定性与性能,建议在输入端和输出端分别配置低 ESR 陶瓷旁路电容,并遵循数据手册中的布局与走线建议以最小化噪声耦合与压降。使能脚用于系统电源管理时,应考虑上电顺序与逻辑电平兼容性。短路与过流保护虽能提高系统鲁棒性,但在热与长期稳定性设计中仍应留有裕量,详细参数与典型应用电路请参见官方数据手册。
SSP7615-12M5R 以其低功耗、低噪声与小体积封装,为便携式与噪声敏感系统提供了高性价比的 1.2V 线性电源解决方案。若需完整电参数、典型曲线及 PCB 布局指导,请联系上海矽朋或参考产品数据手册。

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.
