TMI6030-28 产品概述
一、概述
TMI6030-28 是拓尔微（TMI）推出的一款固定输出 2.8V 线性稳压器，采用 SOT-23-5 小封装，面向对尺寸、效率与可靠性有较高要求的便携与嵌入式应用。器件集成短路保护、过流保护、过热保护以及使能控制，静态电流仅 50µA，最大输出电流可达 300mA，典型压差为 320mV（Iout=300mA），在 1kHz 时 PSRR 达到 70dB，工作结温范围 -40℃~+125℃，输入电压上限 5.5V。
二、主要特点
- 固定输出：2.8V 正输出，适用于对固定电源轨需求的设计；
- 低静态电流：Iq = 50µA，待机功耗低，适合电池供电设备；
- 输出能力：最大 300mA 输出电流，压差 320mV@300mA（低压差设计）；
- 优异的抑制能力：PSRR 70dB@1kHz，有利于降低电源噪声对敏感模拟/射频电路的干扰；
- 保护功能：内置短路保护、过流保护和过热保护，提高系统可靠性；
- 使能控制：带 EN 脚，可由外部逻辑实现电源开关管理；
- 宽温度范围：-40℃~+125℃（Tj），满足工业级温度需求；
- 封装：SOT-23-5，节省 PCB 面积，便于批量生产与表贴工艺。
三、典型应用
- 便携式/电池供电设备（传感器节点、手持终端、可穿戴设备）；
- MCU、传感器和模拟前端供电；
- 无线通信模块、蓝牙/Wi‑Fi 芯片电源轨；
- 工业控制与数据采集模块的局部稳压；
- 需要低噪声、低压差稳压器的精密模拟电路。
四、使用与布局建议
- 输入/输出去耦：建议在输入端和输出端各放置陶瓷电容（例如 1µF～10µF），并尽量靠近器件引脚以抑制瞬态；
- 使能控制：EN 脚用于外部逻辑控制，设计时注意 EN 的电平兼容与上电顺序；
- 散热考虑：SOT-23-5 封装空间有限，需在 PCB 上保留充足铜箔和地平面以改善散热，长时间大电流工作时注意温升；
- 布线要点：Vin、Vout 与 GND 引线要短且宽，避免通过敏感模拟地走高电流回路，同相邻高频或大电流走线保持距离。
五、选型提示
当设计需要固定 2.8V 输出且强调低静态电流、集成保护功能和较好 PSRR 时，TMI6030-28 是一个紧凑且可靠的选择。选型时请结合系统的最大负载电流、输入电压裕量、热条件及使能逻辑要求，参照器件的完整规格书进行详细验证与 PCB 热设计。若需更高电流或可调输出版本，可向供应商咨询相邻产品系列。
如需我帮忙整理一份典型应用原理图草图、PCB 布局注意事项或热仿真建议，请告知电源输入范围与使用场景。

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.
