TMI6050-28 产品概述
一、产品简介
TMI6050-28 是拓尔微（TMI）推出的一款高性价比、固定输出正向低压差线性稳压器（LDO），输出电压固定为 2.8V，最大输出电流可达 600mA。器件采用 SOT-23-5 小型封装，适合对体积、成本和散热有综合要求的便携与工业应用。典型静态电流仅 75µA，适合电池与低功耗系统供电管理。
二、主要特性
- 输出类型：固定（2.8V）
- 最大输出电流：600mA
- 静态电流（Iq）：75µA（典型）
- 压差（Dropout）：600mV @ 600mA
- PSRR：60dB @ 1kHz（良好电源噪声抑制）
- 内建短路保护、过流保护、过热保护
- 带使能（EN）功能，可实现输出使能/关断
- 工作结温范围：-40℃ ~ +125℃（Tj）
- 封装：SOT-23-5
三、电气与热参数要点
- 推荐最大输入电压：不超过 5.5V（请以完整数据手册为准）
- 最低输入电压：应保证 VIN ≥ VOUT + Vdrop（在满载 600mA 时建议预留约 0.6V 余量）
- 低待机电流，适合待机/休眠场景
- 内部热关断与限流机制提高系统可靠性
四、封装与引脚（示意）
封装：SOT-23-5，适合自动贴装与批量生产。常见引脚功能（型号具体引脚排列请参考正式资料）：
- VIN：电源输入
- VOUT：稳压输出（2.8V）
- GND：地
- EN：使能输入（高使能）
- NC/ADJ：保留或空脚
在设计时务必参照厂方封装与引脚图，按规范焊盘与热散布局。
五、典型应用场景
- 电池供电设备、便携式终端与手持仪器
- 物联网节点、传感器前端与低功耗 MCU 供电
- 工业控制模块、通信模块的低压稳压
- 对噪声和稳定性有要求的模拟/混合信号电路
六、设计建议与注意事项
- 输入/输出去耦：建议在 VIN 端和 VOUT 端分别放置低 ESR 陶瓷电容（常见 1µF~10µF，具体容量与 ESR 依数据手册要求选择），以保证稳定性与瞬态响应。
- 留出压差余量：系统设计时需考虑压差随输出电流上升而增大，保证在最大负载下 VIN 足够。
- 散热布局：SOT-23-5 封装受限于封装散热能力，建议使用较宽的地平面或热过孔以降低结温，避免长期满载导致热关断动作。
- 布线：输入与输出电容尽量靠近芯片相应引脚放置，GND 引脚形成低阻抗回流路径。
七、保护功能说明
TMI6050-28 内置短路保护与过流限制，遇异常负载时自动限制输出电流以保护器件与负载；过热保护在结温超过安全值时关闭输出并在温度恢复后自动恢复，配合使能功能可实现可靠的系统级电源管理。
总结：TMI6050-28 以其低静态电流、良好 PSRR、完整的保护功能及小型封装，适用于对能耗、空间与可靠性有综合要求的电源管理场景。选型与电路设计时，请以厂方最新数据手册为准以获得完整电气特性曲线与布局建议。

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.
