SSP7615-30DFR 产品概述
一、产品简介
SSP7615-30DFR 是上海矽朋（Siproin）推出的一款固定输出线性低压差稳压器（LDO），输出电压 3.0V，面向对低静态电流、低噪声和高抑制比有要求的便携及物联网终端供电方案。器件采用超小型 DFN-4 (1×1 mm) 封装，集成使能控制、过流及短路保护，适合空间受限、功耗敏感的应用。
二、主要性能特点
- 固定输出：3.0V 正极输出；单通道。
- 最大工作电压：8V（输入端参考），输出电流可达 400mA。
- 低静态电流：Iq = 450 nA（静态待机态），适合电池供电设备。
- 低压差特性：压差仅 400 mV @ 200 mA（更高电流下压差会相应增加）。
- 电源纹波抑制：PSRR = 60 dB @ 1 kHz，适用于对电源噪声敏感的模拟/射频前端。
- 保护功能：集成过流保护与短路保护；带使能（EN）引脚便于系统电源管理。
- 工作温度范围：-40℃ ~ +85℃（Ta）。
三、封装与机械特性
- 封装：DFN-4（1 × 1 mm），小型化利于高密度 PCB 布局。
- 推荐 PCB 布局：EN/IN/OUT/GND 引脚周围留足过孔并确保裸露散热焊盘与底层铜平面相连，以提升散热能力。
四、典型应用场景
- 便携式设备与可穿戴终端；
- 低功耗物联网节点与传感器模块；
- 模拟前端、射频电路和 ADC/DAC 参考电源；
- 工业控制与测量仪器中对稳定 3.0V 电源的需求。
五、使用注意事项与热管理建议
- 线性稳压器的功耗由 (Vin − Vout) × Iout 决定。若输入 8V、输出 3V 并在 400 mA 工作，功耗约 2.0 W，超小 DFN-4 封装难以散热，应避免长时间在此工况下工作或采用降压预处理。
- 建议使用低 ESR 陶瓷电容做输入/输出旁路（常用值 1 µF ～ 10 µF），并尽量将电容靠近器件引脚放置以保证稳定性与抑制振铃。
- EN 引脚可用于软开关或系统电源管理，分别接高/低电平控制输出开启与关断。
- 在靠近敏感模拟电路时，利用 PSRR 特性并配合良好的布局和接地以获得更佳噪声抑制效果。
六、订购信息与支持
- 型号：SSP7615-30DFR
- 品牌：Siproin（上海矽朋）

Send RFQ
Use the form for single models, category sourcing, and multi-line BOM requirements.
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.
