SPX3819M5-L-5-0 产品概述
SPX3819M5-L-5-0 是 TECH PUBLIC（台舟电子）提供的一款高性能单通道线性稳压器（LDO），为固定输出 5V 的正极输出器件，封装为 SOT-23-5。器件集成使能控制、过流保护与过热保护，适用于便携与工业电源管理，能在宽温度范围内稳定工作。
一、主要特性
- 输出类型：固定（5.0V）
- 输出电流：最高 500 mA
- 工作电压（最大输入）：20 V
- 输出极性：正极
- 使能（EN）管脚：外部逻辑控制开关状态
- 保护功能：过流保护（OCP）、过热保护（OTP）
- 静态电流（Iq）：典型值 5 μA（低静态功耗）
- 工作温度：-40 ℃ 至 +85 ℃（Ta）
- 封装：SOT-23-5，单通道
二、性能亮点
- 低压差：典型压差 350 mV @ 100 mA，有利于低压差供电场景，提升电源效率
- 良好电源抑制：PSRR = 70 dB @ 1 kHz，可有效抑制中频纹波对负载的影响
- 低静态电流特性使其非常适合待机/省电型应用，同时在瞬态时能提供高达 500 mA 的峰值输出能力
三、封装与热特性
- SOT-23-5 小尺寸封装，利于空间受限的板级设计
- 高电流输出时需注意封装热阻和PCB散热，建议在布局时留出散热铜箔并靠近地平面以减少结温上升和热降额
四、典型应用场景
- 移动设备与便携终端的稳压电源
- 工业控制、传感器前端供电
- 通信设备、消费电子的数字/模拟混合供电
- 电池供电系统中的后级稳压
五、使用建议
- 输入和输出端建议并联低ESR陶瓷电容（典型 1 μF~10 μF）以保证稳定性和改善瞬态响应，并将电容尽量靠近器件引脚布局
- 使能管脚通过外部逻辑控制上拉/下拉以实现开关管理，具体逻辑电平请参考器件完整数据手册
- 在高电流工作点注意PCB散热设计与热降额，搭配适当保护电路提高系统可靠性
SPX3819M5-L-5-0 以其低静态电流、良好PSRR 与完整保护功能，适合对空间与功耗敏感但需稳定 5V 电源输出的各种电子产品。若需详细电气特性曲线、引脚定义与典型应用电路，请参考厂商完整数据手册或联系 TECH PUBLIC（台舟电子）技术支持。

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.
