SSP78M05线性稳压器（LDO）产品概述
一、产品核心定位与基础属性
SSP78M05是上海矽朋电子（Siproin）推出的固定输出型线性稳压器（LDO），采用TO-252贴片封装，专为需要稳定、低噪声5V直流供电的场景设计。作为线性稳压方案，其核心优势在于输出纹波小、噪声低，同时集成完善的保护特性，适合对供电质量要求较高的工业、通信及模拟电路领域。
二、关键电气参数解析
SSP78M05的电气参数围绕“稳定输出”与“环境适配”两大核心设计，关键指标清晰支撑实际应用：
- 输入输出范围：最大工作电压35V（输入电压上限），固定输出5V，最大输出电流500mA——可满足单片机、传感器模块等中小功率负载的供电需求，无需额外升压/降压转换；
- 纹波抑制与噪声：电源纹波抑制比（PSRR）达80dB@120Hz，能有效抑制市电整流后常见的120Hz纹波干扰；输出噪声仅40uV（典型值），远低于普通开关电源，适配音频放大器、高精度ADC/DAC等对噪声敏感的模拟电路；
- 压差与静态电流：压差2V@100mA（输入电压需比输出高2V以上才能稳定工作），静态电流5.5mA——在保证输出稳定的前提下，静态功耗处于线性稳压器的合理区间，不会过度消耗系统电源；
- 输出特性：单通道正极输出，无需额外外围电路即可实现短路、过热保护，简化系统设计。
三、封装形式与典型应用场景
SSP78M05采用TO-252封装（DPAK），这是一种贴片式功率封装，具备以下实用特点：
- 体积小巧（3.3mm×6.5mm×2.3mm），适合PCB高密度布局；
- 散热性能优于传统TO-92插件封装，可支持500mA负载下的长期稳定运行。
其典型应用场景覆盖：
- 工业控制：-25℃~+125℃宽温范围适配户外传感器、PLC模块等恶劣环境；
- 通信设备：RS485/CAN总线接口、小型基站的低纹波供电；
- 模拟电路：音频处理电路、高精度称重/温度传感器的低噪声供电；
- 消费电子：智能家电、WiFi/蓝牙模块的辅助5V供电。
四、安全保护特性
SSP78M05内置双重保护机制，提升系统可靠性：
- 短路保护：输出端意外短路时，器件自动进入限流模式（电流限制在安全范围），避免负载或自身烧毁，故障排除后自动恢复；
- 过热保护：结温（Tj）超过阈值时关断输出，防止过热导致性能下降，温度回落至安全范围后恢复正常工作。
五、环境适应性与可靠性总结
SSP78M05的宽温工作范围（-25℃~+125℃）是核心竞争力之一，可覆盖工业级应用的温度要求；线性稳压架构无高频开关干扰，输出纯净度高，适配对EMI敏感的场景。
综上，SSP78M05是一款性价比突出的固定5V线性稳压器，适合中小功率、低噪声、宽温环境下的稳定供电需求，尤其在工业控制、模拟电路等领域具有明显优势。

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.
