LT1761ES5-SD#TRPBF线性稳压器(LDO)产品概述

一、产品核心身份与定位

LT1761ES5-SD#TRPBF是亚德诺半导体(ADI)旗下LINEAR品牌推出的可调输出低压差线性稳压器(LDO),专为低功耗、小体积、宽温环境下的电压调节场景设计。该器件采用TSOT-23-5超小型封装,具备多重保护功能,可满足工业控制、便携式设备、传感器电路等多领域的电源需求。

二、关键性能参数深度解析

作为一款高性能LDO,LT1761ES5-SD#TRPBF的核心参数适配多样化应用场景,关键指标如下:

  • 电压范围:输入电压支持1.5V20V(最大输入电压20V),输出电压通过外部电阻可在**1.22V20V之间连续可调**(以内部1.22V基准电压为核心调节);
  • 输出能力:最大输出电流100mA,可满足多数低功耗负载的供电需求;
  • 低压差特性:在100mA满负载下,压差仅为300mV,即输入电压仅需比输出电压高0.3V即可稳定工作,适配输入输出接近的场景;
  • 低功耗表现:静态电流(Iq)仅20μA,远低于常规LDO的静态电流水平,尤其适合电池供电的便携式设备(如手持仪器、无线传感器节点),可显著延长续航时间;
  • 纹波与噪声抑制:电源纹波抑制比(PSRR)达65dB@120Hz,可有效抑制电源端的低频纹波干扰;输出噪声低至20μVrms,对噪声敏感的电路(如高精度传感器、模拟信号处理单元)友好;
  • 宽温工作能力:结温范围覆盖**-40℃~+125℃**,符合工业级温度标准,可在极端环境下稳定运行。

三、封装与引脚功能说明

LT1761ES5-SD#TRPBF采用TSOT-23-5超小型表面贴装封装(尺寸约2.9mm×2.5mm×1.1mm),引脚定义清晰,具体功能如下:

  1. IN引脚:电源输入引脚,需连接1.5V20V的直流输入电压,建议靠近引脚并联0.1μF1μF陶瓷电容滤波;
  2. OUT引脚:电压输出引脚,需并联1μF~10μF陶瓷电容(或钽电容)稳定输出,输出电压由FB引脚反馈调节;
  3. GND引脚:接地引脚,需可靠连接系统地;
  4. FB引脚:反馈调节引脚,通过外接两个分压电阻(R1、R2)设置输出电压,公式为:( V_{OUT} = 1.22V \times (1 + R1/R2) );
  5. SHDN引脚:关断控制引脚(可选功能),拉低至地可使器件进入关断模式,静态电流降至纳安级(典型1μA以下),进一步节省功耗。

四、多重保护功能保障可靠性

该器件内置三重核心保护机制,提升系统抗干扰与抗异常能力:

  • 过流保护(OCP):当输出电流超过100mA(典型值)时,自动限制输出电流,防止负载短路或过载导致器件损坏;
  • 反接保护:若输入电压极性接反(如电池正负极接反),器件可避免损坏,适合现场安装环境复杂的场景;
  • 过热保护(OTP):当结温超过125℃时,自动关断输出,待温度回落至安全范围后恢复工作,防止过热烧毁。

五、典型应用场景

LT1761ES5-SD#TRPBF的性能特性使其适配多类场景:

  1. 工业控制模块:宽温范围(-40℃~+125℃)适合户外或工业现场的传感器节点、PLC辅助供电;
  2. 便携式设备:低静态电流(20μA)与小封装适合手持仪器、无线耳机、智能手环等电池供电设备;
  3. 低噪声电路:20μVrms低噪声可用于高精度模拟信号处理、医疗传感器(如心电图模块);
  4. 可调电压需求场景:输出电压1.22V~20V可调,可替代固定电压LDO,适配单片机(如3.3V、5V)、ADC参考电压等多种负载。

六、产品优势总结

相较于同类可调LDO,LT1761ES5-SD#TRPBF具备以下核心优势:

  • 低功耗与小体积兼顾:20μA静态电流+TSOT-23-5封装,适配电池供电与小型化设计;
  • 宽电压与低压差:输出1.22V~20V可调,100mA负载下300mV压差,覆盖广电压需求;
  • 高可靠性:工业级宽温+三重保护,适合 harsh 环境;
  • 低噪声与纹波抑制:20μVrms噪声+65dB PSRR,满足敏感电路需求。

该器件凭借均衡的性能与可靠性,成为低功耗可调电源设计的优选方案之一。

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.
