TCR2EF15,LM(CT)线性稳压器产品概述

一、产品核心身份与定位

TCR2EF15,LM(CT)是东芝(TOSHIBA)推出的固定输出型线性稳压器(LDO),专为低功耗、小型化电子设备设计,主打高稳定性、低噪声与宽温适应性。作为单通道正极输出器件,其无需额外配置分压电阻即可输出1.5V固定电压,既简化电路设计,又保证输出精度的一致性。

二、关键性能参数深度解析

1. 电压与电流能力

  • 工作电压:支持最高5.5V输入,覆盖常见电池(3节干电池、单节锂电池)及直流电源场景,适配多种供电来源;
  • 输出电压:1.5V固定输出,无需外部调整,适合对电压精度要求稳定的负载(如部分低功耗MCU、传感器);
  • 输出电流:最大200mA,可满足多数小型无线模块、模拟电路的供电需求,无需额外并联扩展。

2. 纹波与噪声控制

  • PSRR:73dB@1kHz,能有效抑制电源端的高频纹波(如开关电源的输出纹波),减少对敏感模拟电路的干扰;
  • 输出噪声:35uVrms(典型值),属于低噪声LDO范畴,适合音频电路、传感器信号调理等对噪声敏感的应用。

3. 效率与功耗优化

  • 压差:290mV@150mA(典型值),即输入电压仅需比输出电压高约0.3V即可稳定工作,适配电池电压衰减后的场景(如锂电池放电后期);
  • 静态电流:35uA(典型值),远低于普通LDO的静态电流水平,可显著延长纽扣电池、小型锂电池供电设备的续航时间。

三、封装与应用适配性

该器件采用SOT-25-5封装(SMV标识),属于超小型表面贴装封装,尺寸紧凑(约2.9×2.8×1.1mm),适合对空间要求严格的便携设备(如智能手环、蓝牙耳机)或高密度PCB设计。引脚布局简洁,无需额外散热片(最大输出电流200mA,功耗较低),可直接焊接于小型电路板。

四、功能特性与可靠性保障

  1. 过流保护:内置过流保护电路,当输出电流超过额定值(如短路、过载)时,自动限制电流或关断输出,避免器件及负载损坏;
  2. 宽温工作:支持-40℃至+85℃的环境温度(Ta),覆盖工业级与消费级设备的常见温度区间,可用于户外便携设备或室内工业控制模块;
  3. 固定输出优势:无外接电阻调整,电路设计简单,输出电压精度不受外部元件影响,批量应用时一致性更好。

五、典型应用场景

  1. 便携电子设备:智能手环、蓝牙耳机、计步器等低功耗产品,依赖低静态电流延长续航,1.5V输出适配部分MCU、传感器供电;
  2. 模拟信号调理:温度/压力传感器的信号前端电路,利用低噪声特性减少信号干扰,保证测量精度;
  3. 小型工业模块:如小型PLC的I/O节点、远程传感器终端,宽温范围适配工业环境的温度变化;
  4. 消费电子配件:蓝牙音箱的辅助供电、智能手表的传感器供电,紧凑封装适合小型化设计。

TCR2EF15,LM(CT)凭借低功耗、低噪声、宽温适配与小型化优势,成为电池供电设备、模拟电路前端等场景的稳定供电方案,适合对空间、功耗敏感且需要固定1.5V输出的应用需求。

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.

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
