SSP7615-18DFR 产品概述
一、产品简介
SSP7615-18DFR是上海矽朋（Siproin）推出的一款固定输出线性稳压器（LDO），提供正向1.8V输出，最大输出电流400mA。器件针对低功耗与小体积应用优化，具备极低静态电流（典型500nA）、良好的电源纹波抑制（PSRR 60dB）和低压差特性（典型压差约200mV），适合电池供电或对噪声敏感的系统电源管理。
二、主要特性
- 固定输出：1.8V（正极输出）
- 最大输出电流：400mA
- 静态电流（Iq）：典型500nA，适合待机低功耗应用
- 压差（Dropout）：约200mV（在规定电流条件下的典型值）
- PSRR：典型60dB，能有效抑制上游电源纹波
- 保护功能：短路保护与过流保护，增强系统可靠性
- 工作温度范围：-40℃至+125℃（Tj）
- 封装：DFN-4 (1×1 mm)，适合高密度贴装
三、电气性能要点
SSP7615-18DFR在中等负载下保持较低压差，保证在8V工作电源（器件额定工作电压条件）下稳定输出1.8V。高PSRR使其在存在开关电源噪声或长电源线干扰时，仍能为模拟前端或数字核心提供干净电源。500nA的静态电流显著降低系统待机功耗，有利于便携与物联网终端。
四、封装与热管理
采用DFN-4 (1×1 mm)小封装，便于紧凑型PCB设计。尽管器件集成热保护，但在高电流或较大压降条件下仍需关注散热设计：推荐在PCB上增加散热铜箔与必要的过孔，保证芯片结温不超限，特别是在连续400mA输出时需评估功耗（Pd ≈ (Vin – 1.8V) × Iout）。
五、典型应用场景
- 便携式设备与电池供电终端（传感器节点、手持设备）
- 物联网（IoT）模块与无线通信设备的数字核心电源
- 模拟前端、ADC/DAC、低噪声参考电源
- 存储器、微控制器或FPGA低压轨供电
六、设计与布局建议
- 输出端建议配合1µF10µF低ESR陶瓷电容（X5R/X7R），并将电容尽可能靠近输出引脚布局；输入端并联0.1µF1µF去耦电容以抑制高频噪声。
- 保持输入/输出走线最短与最宽，减少压降与寄生阻抗。
- 对于高功率工况，增加PCB散热面积与铜厚，必要时布置散热过孔。
- 在有严格噪声要求的应用中，可在输入端加入合适的滤波网络以提升整体PSRR表现。
七、使用注意事项
- 压差200mV为典型值，实际压差受流量与温度影响，设计时应留有裕量。
- 保护特性能防止短路与过流，但频繁的极限工况可能影响器件寿命，应通过系统设计避免长时间过载。
- 请参照官方数据手册核对引脚定义与典型电气特性，完成最终版图与热设计验证。
SSP7615-18DFR以其超低静态电流、良好的噪声抑制与小型封装，适合对功耗、空间与电源质量有较高要求的现代电子产品电源设计。若需更详细的电气参数和典型波形，请参考厂方完整数据手册或联系供应商技术支持。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
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.
