SSP7615-28DFR 产品概述

一、产品简介

SSP7615-28DFR 是上海矽朋(Siproin)推出的一款固定输出线性稳压器(LDO),输出电压为 2.8V,面向需高精度、低噪声且对尺寸敏感的电源应用场景。器件为单通道正极输出,封装为紧凑的 DFN-4 (1×1) 小体积封装,适合空间受限的便携或板载电源设计。

二、主要性能与特性

  • 输出类型:固定(2.8V)
  • 工作电压:8V
  • 最大输出电流:400mA
  • 静态电流(Iq):典型 500nA,适合低功耗待机应用
  • 压差(Dropout):典型 200mV(在规定工作条件下)
  • 电源纹波抑制比(PSRR):60dB @ 1kHz,有效抑制电源噪声
  • 保护功能:具备过流保护与短路保护,提高系统可靠性
  • 工作温度范围:-40℃ 至 +85℃

三、优势与适用场景

优势:

  • 超低静态电流在待机时能显著延长电池寿命,适合物联网、可穿戴与手持设备;
  • 低压差保证在低压差输入下仍能稳定提供 2.8V 输出,适用于降压后作为清洁电源;
  • 良好的 PSRR 与线性输出特性,适合对噪声敏感的模拟前端与射频模块供电;
  • 过流与短路保护为系统提供硬件级防护,减少故障风险。

典型应用:

  • 电池供电的便携终端、智能穿戴设备、传感器节点
  • 音频、模数混合电路的稳压电源
  • 工业控制与通信设备中的基准/外设电源
  • 高精度模拟电路或射频前端的局部电源

四、封装与布局建议

DFN-4 (1×1) 超小封装有利于高密度 PCB 设计,但对散热与布局要求较高。建议在布局时:

  • 在 PCB 下方预留热沉焊盘并通过热孔或多层铜平面扩散热量;
  • 输出端与输入端靠近电容,按推荐值放置去耦电容以保证稳定性与瞬态响应;
  • 参考器件完整 datasheet 选择合适的输出电容类型与 ESR,确保环路稳定。

五、选型与扩展提示

在选型时需注意系统输入电压裕量(确保 Vin ≥ Vout + 压差),以及在最大负载时的热耗散评估。若系统对效率要求极高或需大电流输出,可考虑配合开关转换器与后端 LDO 组合使用,以兼顾效率与噪声性能。详细电气参数、典型特性曲线及封装引脚定义请参阅 SSP7615-28DFR 的官方 datasheet,或联系上海矽朋获取技术支持与样片。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
