TCR2EF18,LM(CT)线性稳压器产品概述

一、产品定位与核心身份

TCR2EF18,LM(CT)是东芝推出的固定输出线性稳压器,属于电源管理IC(PMIC)范畴,专为需要稳定1.8V供电、低功耗、小封装的电子设备设计。其核心定位是“小电流、低噪声、高可靠性”的稳压方案,覆盖消费类、工业级等多场景应用,无需复杂外围电路即可实现稳定供电。

二、关键性能参数深度解析

该器件的参数围绕“稳定供电+低功耗+抗干扰”核心需求设计,具体特性如下:

1. 输出与负载能力

  • 固定输出电压1.8V(精度满足多数数字/模拟电路需求),最大输出电流200mA,可覆盖小型MCU、传感器等负载;
  • 压差特性:150mA负载下压差仅230mV,意味着输入电压只需略高于输出(如输入2.03V即可满足150mA输出),适合低电压电池供电场景。

2. 功耗与效率

  • 静态电流(Iq)仅35μA,远低于传统线性稳压器的平均水平,待机功耗极低——以1000mAh电池为例,待机时仅需约28.57天(理论值)即可耗尽,是便携式设备(如智能穿戴)延长续航的关键优势;
  • 线性稳压器无开关噪声,配合低静态电流,可实现“安静”供电,避免干扰数字电路逻辑。

3. 纹波与噪声控制

  • 电源纹波抑制比(PSRR)达73dB@1kHz,能有效抑制输入电源的高频纹波(如开关电源的输出纹波),确保输出电压波动控制在极小范围;
  • 输出噪声低至35μVrms,适合对噪声敏感的模拟电路(如传感器信号调理、音频前端),避免噪声干扰信号采集精度(例如温度传感器的±0.1℃精度需求)。

4. 保护与环境适应性

  • 内置过流保护(OCP),负载短路时自动限流(约250mA左右),防止器件及负载损坏,提升系统可靠性;
  • 工作温度范围宽(-40℃~+85℃),满足工业级环境(如户外传感器、车载辅助设备)的温度需求;
  • 单通道正极输出,电路设计简单,无需额外配置负电源,降低PCB设计复杂度。

三、封装与可靠性设计

采用SOT-25-5封装,尺寸小巧(约2.9mm×2.8mm×1.1mm),适合空间受限的PCB设计(如智能手环、蓝牙耳机的主板);封装引脚布局合理,散热性能满足200mA负载下的热需求,无需额外散热片,进一步节省空间。

四、典型应用场景

结合参数特性,该器件的核心应用场景包括:

  1. 便携式电子设备:智能手环、蓝牙耳机、小型MP3播放器等,低静态电流延长电池续航,小封装适配紧凑结构;
  2. 传感器模块:温度传感器、压力传感器、气体传感器等,低噪声保证信号采集精度,宽温范围适应户外/工业环境;
  3. 工业控制单元:小型PLC的辅助电源、电机驱动控制电路等,过流保护提升系统可靠性,宽温范围满足 harsh 环境;
  4. 消费类电子配件:遥控器、智能插座、小型游戏机等,固定1.8V输出匹配多数MCU(如STM32L系列)的供电需求。

五、核心选型优势

与同类同规格线性稳压器相比,TCR2EF18,LM(CT)的优势集中在:

  • 低静态电流:35μA远低于竞品(部分竞品达100μA以上),待机功耗降低65%;
  • 低噪声:35μVrms输出噪声,适合模拟电路的高精度需求;
  • 宽温范围:-40℃+85℃覆盖工业级场景,竞品多为0℃70℃(商业级);
  • 小封装:SOT-25-5体积小,适配高密度PCB设计。

总结

TCR2EF18,LM(CT)作为东芝的高性价比线性稳压器,以“低功耗、低噪声、宽温范围、小封装”为核心优势,精准匹配小型电子设备的稳压需求。无论是便携式消费类产品的续航优化,还是工业传感器的信号稳定,均能提供可靠的1.8V供电方案,是同类场景下的优选器件之一。

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.
