TMI6030C-18 产品概述
一、产品简介
TMI6030C-18 为拓尔微（TMI）推出的一款固定输出线性稳压器，输出电压为 1.8V，单通道正极输出设计。器件采用 SOT-23 小封装，面向空间受限和低功耗应用场景，能够以简洁外围实现稳定、低噪声的电源输出。
二、主要电气性能
- 输出类型：固定（1.8V）
- 工作电压：5.5V（器件允许的最高工作电压）
- 输出电流：最大 300mA
- 电源纹波抑制比（PSRR）：70dB @ 1kHz（对抑制电源纹波和高频干扰有较好效果）
- 输出极性：正极
- 输出通道数：1
三、保护与可靠性特性
TMI6030C-18 集成多重保护机制以提高系统可靠性：
- 过流保护（OCP）：在输出过载或异常电流增大时限制输出电流，防止器件及负载损坏。
- 短路保护：当输出短路发生时自动进入保护状态，降低热应力与损坏风险。
- 热关断：芯片结温升高至设定阈值时触发热关断，待温度恢复后自动恢复输出。 额定工作温度范围为 -40℃ ~ +125℃（Tj），适用于工业级环境。
四、应用场景
TMI6030C-18 适合以下典型应用：
- MCU、FPGA 等数字核心电源 1.8V 轨
- 传感器、模拟前端及混合信号电路，因其高 PSRR 能有效降低噪声耦合
- 电池供电设备、便携式终端与物联网节点（空间受限的电源管理方案）
- 工业控制与嵌入式系统中需稳定低压源的场合
五、封装与 PCB 设计建议
器件采用 SOT-23 小外形封装，便于表面贴装与高速产线加工。为获得最佳热性能与电气稳定性，建议：
- 在输入端和输出端靠近引脚放置低 ESR 陶瓷旁路电容（例如 1µF～10µF 范围，视具体负载与纹波要求调整），并确保电容尽量贴近器件引脚以减少寄生阻抗。
- 输入电容和输出电容的地回路应尽可能短且粗，采用地平面或大面积铜箔以利散热。
- SOT-23 封装热量主要通过引脚及顶层铜箔散出，必要时在 PCB 下方与周围增加铜箔或多层过孔以增强散热能力。
六、选型与使用注意事项
- 请确认系统最大输入电压不超过器件允许值（工作电压 5.5V）。
- 根据系统负载与效率需求选择合适的输入/输出电容及滤波方案，以发挥器件的高 PSRR 特性。
- 在有严格噪声或瞬态响应要求的应用中，应结合外围元件与 PCB 布局一并验证动态性能与稳定性。
- 参考厂商完整数据手册获取引脚定义、典型电路、热阻参数及可靠性测试数据，确保设计满足电气与环境要求。

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.
