TPAP2112K-3.3TRG1 产品概述
一、概述
TPAP2112K-3.3TRG1 是 TECH PUBLIC（台舟电子）推出的一款固定输出 3.3V 线性稳压器（LDO），采用 SOT-23-5 封装，面向需要高效率、低噪声和小尺寸的电源应用。器件设计重点在于低静态电流与较高输出电流能力，适合电池供电与嵌入式终端等场景。
二、主要特性
- 固定输出：3.3V 正极输出
- 输出电流：最大 600mA
- 静态电流 (Iq)：10 μA（典型值）——非常适合低功耗待机应用
- 压差（Dropout）：320 mV @ 600 mA（满载时低压差）
- PSRR：80 dB @ 100 Hz —— 优异的电源纹波抑制能力
- 保护功能：具备过流保护与过热保护，提高系统可靠性
- 工作温度：-40 ℃ 至 +85 ℃（Ta）
- 工作电压：最高 5.5 V 输入电压支持
- 封装：SOT-23-5，适合体积受限的电路板设计
三、电气性能要点
TPAP2112K-3.3TRG1 在 100 Hz 下可提供约 80 dB 的 PSRR，对于噪声敏感的模拟、RF 前端或 ADC/DAC 供电尤为有利。满载 600 mA 时压差仅 320 mV，可在较低的输入-输出差压下维持稳定输出，有助于延长电池使用时间或在单节锂电池供电时获得更高可用电压余量。
四、保护与可靠性
器件内置过流保护（OCP）和过热保护（OTP），可在短路或过载情况下限制输出电流并在温度异常时自动关闭输出以防损坏，适合对可靠性要求较高的工业与消费类产品。
五、封装与热管理
SOT-23-5 小型封装适合空间受限的应用，但在高电流工作（接近 600 mA）时需注意 PCB 热耗散设计。建议在 GND 处使用大面积铜箔或加焊盘以改善散热，必要时将热敏感元件远离稳压器以降低热累积。
六、典型应用
- 便携式与电池供电设备（物联网终端、传感器节点）
- 工业与消费类数字电路的 3.3V 供电
- 模拟前端与 RF 模块的低噪声供电
- 单板微控制器、电机驱动逻辑电源等
七、使用建议
- 输入端靠近器件放置去耦电容以抑制输入纹波；输出端使用低 ESR 陶瓷电容（例如 1–10 μF）以确保稳压器稳定与良好瞬态响应。
- 若在高电流条件下长时间工作，应在 PCB 上预留足够散热铜面积并评估温升。
- 在系统设计中考虑满载时的最小输入电压（VOUT + Vdrop），满载情况下需确保输入电压 ≥ 3.3 V + 0.32 V ≈ 3.62 V，以保证 600 mA 输出能力。
总结：TPAP2112K-3.3TRG1 以其低静态电流、良好 PSRR 和较低压差，为对噪声、功耗与尺寸有要求的 3.3V 供电场景提供了稳健且经济的解决方案。若需更详细的电气特性、引脚排列或典型应用电路，请参考产品数据手册。

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.
