SSP1117-2.5V线性稳压器(LDO)产品概述

一、产品核心身份与定位

SSP1117-2.5V是上海矽朋(Siproin)推出的固定输出型线性稳压器(LDO),属于中低功率稳压器件范畴,专为需要稳定2.5V直流电源的电子设备设计。该器件采用低压差设计,兼顾小体积与可靠性,适用于消费电子、工业控制、通信等多领域的稳压场景,是替代传统高压差线性稳压器的高性价比选择。

二、关键电气性能参数

该LDO的核心参数明确,可满足多数常规稳压需求:

  1. 输入输出特性:输入工作电压最大为20V,固定输出电压2.5V,输出极性为正极,单通道输出;
  2. 负载能力与压差:最大输出电流1A,在额定1A负载下的压差仅1.5V(即输入电压只需比输出高1.5V即可稳定输出),远优于传统线性稳压器的高压差表现;
  3. 静态功耗:典型静态电流(Iq)为2mA,轻载时功耗低,适合电池供电或低功耗设备;
  4. 保护特性:内部集成过热保护功能,当器件结温过高时自动关断输出,防止过温损坏,温度恢复后自动重启;
  5. 温度范围:工作环境温度(Ta)覆盖-20℃至+85℃,满足工业级常规环境及消费电子的温度需求。

三、封装特性与可靠性设计

SSP1117-2.5V采用SOT-223贴片封装,具备以下优势:

  1. 体积与集成度:封装尺寸紧凑(典型尺寸约6.5×3.5mm),适合小型化设备的PCB布局,引脚数为3脚(输入IN、输出OUT、地GND),接线简单;
  2. 散热性能:相比SOT-23等小封装,SOT-223的散热面积更大,可有效散发布1A负载时的功耗(1.5V压差×1A=1.5W),常规环境下无需额外散热片;
  3. 可靠性保障:封装采用耐高温材料,配合内部过热保护电路,可在-20℃至+85℃范围内稳定工作,降低器件失效风险。

四、典型应用场景

基于参数特性,该器件适用于以下场景:

  1. 消费电子:便携式设备(如小型蓝牙音箱、智能手环辅助电路)、移动电源稳压模块、数码产品电源转换;
  2. 工业控制:小型传感器模块(温度/压力传感器)、PLC辅助电路、工业仪表2.5V供电;
  3. 通信设备:低功率射频模块(蓝牙4.0)、WiFi模块、小型基站辅助电源;
  4. 汽车电子(辅助):车载USB充电辅助电路、仪表盘小功率显示模块、车载传感器稳压(满足-20℃至+85℃环境);
  5. 电源适配器:5V/12V转2.5V的小型稳压电路,替代传统7805等高压差稳压器。

五、应用选型与注意事项

为确保稳定工作,需注意以下要点:

  1. 输入电压范围:输入需≥输出电压+压差(1A负载时≥4V),最大不超过20V,避免过压;
  2. 负载电流限制:最大输出1A,禁止长期过载,需更大负载时可并联或选更高功率器件;
  3. 散热设计:1A负载功耗1.5W,PCB需加宽输入/输出引脚铜箔(≥10mm²),或增加底部散热焊盘;
  4. 输出电容配置:输出端并联10μF以上陶瓷/电解电容,提升电压稳定性、抑制纹波;
  5. 温度适配:工作温度不超过+85℃,高温环境下需增加散热片或降低负载电流。

该器件以高性价比、小体积、低压差为核心优势,可快速匹配多领域的2.5V稳压需求,是中小功率电源设计的实用选择。

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
