TMI6030C-33 产品概述

一、概述

TMI6030C-33 是拓尔微(TMI)推出的一款高性能固定输出线性稳压器,输出电压固定为 3.3V,输出电流可达 300mA。器件采用 SOT-23-5 小封装,面向对尺寸、噪声与功耗有严格要求的便携及嵌入式应用场景。其低压差(320mV@300mA)、低静态电流(Iq = 35μA)和优秀的电源纹波抑制比(PSRR = 70dB @1kHz)使其适合电池供电或对信号完整性敏感的系统。

二、主要性能指标

  • 输出类型:固定(3.3V)
  • 最大输出电流:300mA
  • 工作电压(输入):5.5V(器件最大工作电压)
  • 压降(典型):320mV @ 300mA
  • 静态电流(Iq):35μA(典型)
  • PSRR:70dB @ 1kHz
  • 输出极性:正极、单通道
  • 工作温度范围:-40 ℃ ~ +85 ℃(Ta)
  • 封装:SOT-23-5

三、典型应用

  • 手持与便携式设备的 3.3V 供电轨(传感器、MCU、低功耗外设)
  • 对噪声敏感的模拟前端与射频模块(利用高 PSRR 抑制电源纹波)
  • 电池管理与电压降压后补偿电源
  • 工业控制与物联网终端(需宽温与低静态电流特性)

四、封装与热管理建议

器件采用 SOT-23-5 小封装,适合空间受限的 PCB 布局。由于封装尺寸限制,散热能力有限,建议在 PCB 设计时:

  • 在器件下方和周围布置较大铜箔散热岛,增加层间过孔以提升热传导;
  • 将高耗散器件与 LDO 适当分离,避免局部过热;
  • 在高负载工况下进行热仿真与实际温升测试,保证在最大输出电流与最高环境温度下仍满足热稳定性要求。

五、使用与电路设计要点

  • 输入电压裕量:为保证在最大负载下仍能维持 3.3V 输出,输入电压需高于 3.3V 加上压差(示例:在 300mA 时 Vin 最低约 3.3V + 0.32V ≈ 3.62V);实际设计留有余量以覆盖瞬态与容差。
  • 输出电容与稳定性:建议使用低 ESR 陶瓷或钛电容作输出旁路(常见 1μF~10μF),并遵循厂商关于电容类型与容量的推荐以保证环路稳定。
  • 输入去耦:靠近器件的输入侧放置适当的旁路电容,可抑制输入源内阻与瞬态干扰。
  • 启动与负载瞬态:注意负载突变时的瞬态响应,必要时在负载侧增加去耦或软启动方案以减少输出扰动。
  • 环境与可靠性:遵守器件工作温度范围,避免长期在高温、高功率损耗下运行,以延长可靠性和寿命。

六、封装与型号信息

  • 型号:TMI6030C-33
  • 品牌:TMI(拓尔微)
  • 封装:SOT-23-5(单通道、正极输出)

总结:TMI6030C-33 以其低压差、低静态电流和优异的 PSRR,在体积受限且对噪声、功耗有要求的系统中表现出色。合理的 PCB 热设计与电容选型可充分发挥其性能,是移动终端、物联网与模拟前端电源设计的良好选择。若需详细电气特性曲线、引脚定义与典型应用电路,请参考芯片完整数据手册或联系供应商获取样片与参考设计。

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.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
