SSP7901P36PR 产品概述
一、产品简介
SSP7901P36PR 是上海矽朋（Siproin）推出的一款高输入耐压、低静态电流的固定输出线性稳压器（LDO），输出电压为 3.6V，最大输出电流 300mA。器件集成热关断、短路保护与过流保护，适合对噪声、可靠性和功耗有较高要求的电源设计。
二、主要规格与特性
- 输出类型：固定，正极输出 3.6V
- 工作输入电压：适配高压输入（产品标称可工作至 36V；部分资料标注 40V，具体以规格书为准）
- 最大输出电流：300mA
- 压差（Dropout）：约 1.38V @ 300mA
- 静态电流（Iq）：1.6µA（超低静态电流，利于电池供电系统）
- 电源纹波抑制比（PSRR）：70dB @ 10Hz，55dB @ 1kHz（低频及工频噪声抑制良好）
- 保护功能：热关断、短路保护、过流保护
- 工作温度范围：-40℃ ~ +85℃（Ta）
- 输出通道数：单通道
- 封装：SOT-89-3L
三、优势与设计注意事项
- 低静态电流有利于待机或电池供电应用，可显著降低静态功耗。
- 优秀的低频 PSRR 有助于减少系统噪声对敏感模拟电路或 ADC 的影响。
- 设计时需关注功耗与散热：稳压器耗散功率约为 (Vin - 3.6V) × Iout，满载时若 Vin 较高，需在 PCB 中增加铜箔面积或采用合适散热方案以避免触发热关断。
- 输入与输出端建议放置去耦电容（例如 1µF~10µF），并靠近引脚布置；输出电容的容值与等效串联电阻（ESR）会影响稳压器稳定性，具体数值请参照产品规格书推荐。
四、典型应用场景
- 工业控制与数据采集模块
- 电池供电设备与便携式仪表
- 通信、传感器和微控制器供电电源
- 对低噪声电源有要求的模拟前端与 ADC 供电
五、封装与引脚（概述）
SOT-89-3L 小型封装，适合空间受限应用。典型引脚功能为 Vin、GND、Vout（具体引脚排列与焊盘尺寸请参考规格书）。该封装利于中等功率散热，但高 Vin 高负载情形下仍需配合 PCB 散热设计。
六、结论与建议
SSP7901P36PR 以其高输入耐压、低静态电流与良好 PSRR，在需要稳健保护与低噪声输出的中低功率场合具有竞争力。建议在最终设计前阅读完整版数据手册，确认最大额定值、典型特性曲线及推荐外部元件，以确保电路稳定与可靠。若系统需更高效率或更大电流，应综合考虑开关稳压器或并联/降额设计。

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.
