TMI6050 可调低压差线性稳压器 — 产品概述

一、产品简介

TMI6050 是拓尔微(TMI)推出的一款单通道可调输出低压差线性稳压器,适用于对噪声、功耗和体积有较高要求的电源场景。器件支持 0.8V~5.0V 可调输出,最大输出电流可达 600mA,输入工作电压为 5.5V,工作结温范围 -40℃~+125℃。器件封装为 SOT-23-5,便于便携设备与模块化电源板集成。

二、主要特性

  • 输出类型:可调,输出范围 0.8V ~ 5.0V(最低调整点约 0.8V,具体参考数据手册)
  • 最大输出电流:600mA
  • 静态电流(Iq):约 90µA,适合电池供电或低功耗设计
  • 压差(Dropout):约 700mV @ 600mA(满载条件下)
  • 电源纹波抑制比(PSRR):60dB @ 1kHz,具有良好纹波抑制能力
  • 保护功能:过流保护(OCP)、过热保护(热关断)
  • 输出极性:正极输出
  • 工作电压上限:5.5V
  • 封装:SOT-23-5,单通道设计

三、典型应用场景

  • 移动电源与便携式设备电源管理
  • 电池供电的传感器与模块(MCU、蓝牙/Wi‑Fi 模块等)
  • 对噪声敏感的模拟电路/射频前端电源
  • 工业控制与IoT终端低功耗电源设计

四、典型引脚与可调输出设置(参考)

典型引脚功能(具体引脚排列请以官方数据手册为准):VIN、VOUT、GND、ADJ/FB、EN(或 SHDN,可选)。
可调输出常采用反馈电阻分压设置,参考公式(基于器件参考电压约 0.8V):
VOUT ≈ VREF × (1 + R1/R2)
其中 VREF 典型≈0.8V,实际设计时请参照器件数据手册中给出的精确参考值与调整误差。

五、设计要点与注意事项

  • 散热与功耗:线性稳压器的功耗等于 (VIN − VOUT) × IOUT。在大电流或大压差工况下功耗显著,需通过增大 PCB 铜箔面积、加热沉或减少压差来控制结温,避免触发热关断。
  • 输出电容与稳定性:稳压器对输出电容与 ESR 敏感,建议在输入端和输出端均置入低 ESR 陶瓷电容(一般 1µF~10µF 作参考),具体容量与 ESR 要求请参照产品手册中的稳定性规范。
  • 滤波与去耦:为发挥 60dB@1kHz 的 PSRR,建议在输入端增加足够的去耦与滤波,尤其在开关电源后级或高噪声环境中。
  • 保护与可靠性:器件具有过流与过热保护,但不应依赖保护作为常态工作手段。设计时应设置合理的软启动/限流与外部保护以提升系统可靠性。
  • 启用/关断控制:若使用 EN/SHDN 引脚,可实现外部使能控制与低功耗关断,注意该引脚的电平阈值。

六、热设计与可靠性建议

在最大输出 600mA 与较大 Vin−Vout 条件下,SOT-23-5 封装的散热能力有限。建议:

  • 计算最大功耗并评估结温:Pd = (Vin − Vout) × Iout;
  • 在 PCB 布局中增加散热铜箔(尤其为 GND 与 VOUT 引脚附近),并使用多层板与热过孔改善散热;
  • 若长时间工作在高负载工况,考虑降额使用或采用更大散热能力的封装/外部散热措施。

七、小结

TMI6050 以其宽可调范围、较低静态电流、良好 PSRR 与完整的保护功能,适合用于对噪声与效率有要求的电源设计。合适的外部电容、合理的热设计与按数据手册选择反馈电阻,可保证器件在实际应用中稳定可靠运行。欲获取精确引脚定义、电气特性曲线及应用电路,请参考拓尔微官方数据手册。

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.
