TP5108E23E-33 产品概述
一、产品简介
TP5108E23E-33 是台舟电子（TECH PUBLIC）推出的一款固定输出线性稳压器（LDO），输出电压为 3.3V，集成使能（EN）功能，采用紧凑的 SOT-23-5 封装。器件针对便携与空间受限的系统设计，提供低静态电流、较高输出能力与良好的电源抑制性能，适合为微控制器、射频前端、传感器等模块提供稳定低噪声的电源。
二、主要特性
- 固定输出：3.3V
- 带使能功能（EN），便于系统电源管理
- 静态电流（Iq）：80 μA（低待机功耗）
- 最大输出电流：500 mA
- 压差（Dropout）：300 mV @ 200 mA
- 电源纹波抑制比（PSRR）：70 dB @ 1 kHz
- 输出噪声：50 μVrms
- 工作温度范围：-40℃ ~ +85℃（Ta）
- 封装：SOT-23-5，单通道设计，正极输出
三、电气性能与典型指标
TP5108E23E-33 在中等负载下表现出较低的压差与优良的纹波抑制能力，70 dB @1 kHz 的 PSRR 使其在抑制来自开关电源或其他噪声源的干扰方面具备优势；50 μVrms 的输出噪声适合对噪声敏感的模拟或射频电路。示例计算：当输入电压较高时，器件的功耗按 (Vin - 3.3V) × Iout 计算，请据此评估散热。
四、封装与引脚说明
器件采用 SOT-23-5 小封装，适合表面贴装和高密度 PCB 布局。常见引脚功能包括：VIN（输入）、GND（地）、VOUT（输出）、EN（使能）、NC 或备用引脚（具体引脚排列请参考厂方数据手册）。SOT-23-5 的尺寸与引脚布局有利于空间受限设计，但需注意铜面积与散热路径的配合。
五、应用场景与优势
- 便携设备电源管理：低静态电流延长待机时间
- MCU 与数字逻辑供电：稳定 3.3V 输出满足广泛数字电路需求
- 射频/模拟前端：低噪声与高 PSRR 有助于提升信号质量
- 传感器与数据采集模块：减少电源引入的误差与干扰 相较于开关稳压器，TP5108E23E-33 提供更简单的外围设计与更低的输出噪声，适合对噪声敏感且功率效率要求不极端的场合。
六、热设计与使用建议
- 输入电压与负载电流决定功耗，请评估 (Vin - 3.3V)×Iout 导致的功耗，并保证器件结温在安全范围内。例：若 Vin=5V、Iout=500 mA，则功耗约为 0.85W，需要合适的 PCB 散热。
- 推荐在输入端放置旁路电容以改善瞬态响应和稳定性；输出端采用低 ESR 电容可提升系统稳定性与降低噪声。具体电容值与类型请参照产品数据手册与应用指南。
- 合理使用 EN 引脚进行系统上电顺序控制，可实现外部电源管理与低功耗模式切换。

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.
