XTP2021-180AD1CT 低压差线性稳压器（LDO）产品概述
XTP2021-180AD1CT是芯天下（XTX）针对空间受限、功耗敏感场景推出的固定输出LDO，聚焦便携设备、物联网节点等领域的供电需求，具备超小封装、超低静态电流、低压差及多重保护等核心特性，可有效简化系统设计并延长电池续航。
一、产品定位与核心价值
该器件围绕“小尺寸、低功耗、高可靠性”三大方向优化，解决传统LDO在便携设备中空间占比大、待机功耗高的痛点：
- 超低静态电流：1uA的待机电流相比同类产品平均低30%，适合一次电池供电的长期待机设备；
- 超小封装：DFN1x1-4L封装比常规SOT-23小60%，适配高密度PCB布局；
- 低压差设计：满载300mA时压差仅180mV，支持3.7V锂电池放电至2.0V仍稳定输出；
- 集成保护：无需额外外围电路即可实现使能控制、过流/过热保护，降低系统复杂度。
二、关键性能参数详解
参数项 典型值 应用说明 输入电压范围 2.0V~5.5V 覆盖锂电池（3.7V）、5V系统等常见供电场景 输出电压 1.8V±1% 固定精度满足MCU、传感器等核心器件需求 最大输出电流 300mA 可驱动蓝牙模块、低功耗MCU等中等负载 压差（@300mA） 180mV 低压差保障低输入电压下稳定输出 静态电流（Iq） 1uA 待机功耗极低，延长电池续航（如物联网节点） 工作温度范围 -40℃~+85℃ 工业级温度，满足户外/ harsh环境需求 输出纹波（@100mA） ≤20mV 低纹波适合对噪声敏感的模拟电路（如传感器）三、封装与物理特性
XTP2021采用DFN1x1-4L无引脚封装，具有以下优势：
- 尺寸：1.0mm×1.0mm×0.5mm（高度），适配0402小型化元件的PCB设计；
- 引脚定义（典型）：
1脚：EN（使能控制，高电平有效）；
2脚：OUT（1.8V输出）；
3脚：GND（接地）；
4脚：IN（输入电压）； - 散热：通过焊盘直接散热，比SOT封装效率提升40%，支持连续满载工作。
四、典型应用场景
结合参数特性，该器件适用于以下场景：
- 可穿戴设备：智能手环、手表、健康监测器（小空间+低功耗需求）；
- 物联网（IoT）节点：环境传感器、低功耗MCU节点（1uA Iq延长电池寿命）；
- TWS蓝牙耳机：耳机端供电（小封装+低纹波）；
- 工业低功耗模块：小型数据采集器、无线传感器（-40~85℃工业级温度）；
- 便携式医疗设备：血糖监测仪、小型听诊器（稳定输出+低功耗）。
五、安全保护机制
集成多重保护，保障系统可靠性：
- 过流保护（OCP）：输出电流超350mA时，自动限制至300mA左右，防止负载短路损坏；
- 过热保护（OTP）：结温超150℃时关断输出，温度降至120℃自动恢复，避免热损坏；
- 使能控制：EN低电平时进入关断模式，静态电流降至0.1uA以下；无需使能时可直接接IN脚。
六、应用设计建议
为优化性能，设计需注意：
- 输入电容：IN脚并联1uF陶瓷电容（0402封装），靠近器件滤除纹波；
- 输出电容：OUT脚并联1uF陶瓷电容，稳定输出电压；
- PCB布局：IN/OUT/GND引脚焊盘尽量靠近，减少走线阻抗；
- 使能引脚：避免悬空，不使用时接IN或GND，防止误触发。
XTP2021-180AD1CT凭借超小封装、超低功耗及高可靠性，成为便携电子、物联网等领域的理想供电方案，可有效提升产品竞争力。

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.
