SSP7615-33M5R 产品概述
一、产品简介
SSP7615-33M5R 是上海矽朋（Siproin）推出的一款高性能固定输出线性稳压器（LDO），输出电压为 +3.3V，适用于空间与成本受限的便携和嵌入式系统设计。该器件封装为 SOT-23-5，具备低静态电流与多重保护功能，适合对功耗与可靠性有较高要求的应用。
二、主要特性
- 输出类型：固定（3.3V 正极输出）
- 工作电压：8V（输入侧工作条件）
- 最大输出电流：400mA
- 静态电流（Iq）：450nA（超低待机功耗）
- 压降（Dropout）：400mV @ 200mA（在更高负载下压降会相应增加）
- 电源纹波抑制比（PSRR）：60dB @ 1kHz
- 保护功能：过流保护（OCP）、短路保护（SCP）
- 工作温度范围：-40°C ~ +85°C（Ta）
- 封装：SOT-23-5
三、性能与设计亮点
- 极低待机电流（450nA）非常适合电池供电与待机时间敏感的终端设备，可在待机模式下最大限度降低耗电。
- 在中等负载（200mA）下仅约0.4V 的压差，有助于在较低输入电压条件下维持 3.3V 输出，提升电源效率。
- 60dB 的 PSRR（1kHz）为模拟前端和 RF 电路提供良好噪声抑制，降低电源干扰带来的系统性能退化。
- 集成过流与短路保护，提高系统可靠性，简化外围保护电路设计。
四、典型应用
- 电池供电设备（遥控器、可穿戴、便携式仪表）
- 工业与楼宇控制模块的嵌入式电源
- MCU、传感器和射频前端的稳压供电
- 消费类电子的低功耗子系统
五、外部元件与注意事项
- 输入侧建议并联一枚 1μF 以上低等效串联电阻（ESR）陶瓷电容以抑制输入纹波并稳定 LDO；输出端建议使用 1μF–10μF 低ESR 陶瓷电容以保证环路稳定性与瞬态响应。具体电容值应在评估板上验证。
- 输出电流接近 400mA 时，器件会发热；SOT-23-5 封装的散热能力有限，需在 PCB 布局上通过加大铜箔面积、使用散热过孔或热沉来改善散热。
- 将输入端与输出端电容尽量靠近器件引脚布局，缩短回流路径，减小寄生电感和噪声耦合。
- 若在高温或高功率工况下使用，需评估热升并确保结温在安全范围内。
六、封装与采购信息
- 品牌：Siproin（上海矽朋）
- 型号：SSP7615-33M5R
- 封装：SOT-23-5，适合小尺寸 PCB 设计与自动贴装生产
总结：SSP7615-33M5R 以其超低静态电流、良好 PSRR、完整的保护功能和紧凑封装，适合电池驱动与噪声敏感的嵌入式应用。设计时重点关注输出电容选择与 PCB 热管理可确保器件稳定可靠运行。若需详细电气特性曲线与典型应用电路，建议参考厂商数据手册或联系客服获取评估板资料。

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.
