LR6302B36M 低压差线性稳压器(LDO)产品概述

LR6302B36M是乐山无线电(LRC)推出的固定输出型低压差线性稳压器,针对低功耗、高纯净度电源需求设计,兼具宽输入电压范围、低静态电流、低噪声等核心特性,适用于工业控制、车载电子、高精度模拟电路等多场景。

一、产品定位与核心优势

LR6302B36M定位于中小功率稳定电源解决方案,核心优势可概括为「四低两宽一全」:

  • 低静态电流:仅2μA,大幅降低待机功耗,适配电池供电或长期待机设备;
  • 低输出噪声:27μVrms,满足射频、音频等噪声敏感型应用;
  • 低压差:160mV@100mA(轻/中载下输入仅需略高于输出即可稳定);
  • 低纹波干扰:65dB@1kHz PSRR,有效抑制输入电源纹波;
  • 宽输入电压:最大18V,兼容多种电源输入(如电池组、开关电源);
  • 宽工作温度:-40℃~+125℃(结温),覆盖工业/车载恶劣环境;
  • 全保护功能:过流、过热、短路三重保护,提升系统可靠性。

二、关键电气性能参数解析

1. 输入输出特性

  • 固定输出电压:3.6V(精度符合LRC产品规范);
  • 最大输出电流:300mA,可满足多数中小功率负载(如传感器、MCU、通信模块);
  • 输入电压范围:适配≤18V的电源输入,支持多节锂电池(如5节锂电池总电压≤18V)、线性电源等。

2. 静态电流与效率

静态电流(Iq)仅2μA,远低于常规LDO(通常10μA以上),在负载电流为0时,待机功耗仅0.072mW(18V×2μA),对电池续航提升显著。

3. 纹波抑制与噪声控制

  • PSRR:65dB@1kHz,可将输入电源1kHz纹波抑制99.99%以上,输出电压纯净度高;
  • 输出噪声:27μVrms(典型值),属于低噪声LDO范畴,适合ADC/DAC、射频前端等对噪声敏感的模拟电路。

4. 压差特性

160mV@100mA的压差意味着:当负载电流为100mA时,输入电压仅需达到3.76V(3.6V+160mV)即可稳定输出3.6V,相比传统LDO(压差通常数百mV至1V),在低输入电压场景下效率更高。

三、全面的保护功能设计

LR6302B36M内置三重保护机制,保障器件与负载安全:

  • 过流保护(OCP):当输出电流超过阈值时,自动限制电流(典型值≤350mA),防止负载短路或过载损坏器件;
  • 过热保护(OTP):当结温(Tj)超过150℃左右时,关断输出,避免热失控;温度降低后自动恢复;
  • 短路保护(SCP):输出短路时,限制输出电流至安全范围(典型值≤100mA),持续保护器件不受损坏。

四、工作温度与可靠性

产品支持**-40℃+125℃结温范围**,符合工业级(-40+85℃)及车载级(-40~+125℃)温度要求,可在户外、高温车间、车载环境等恶劣场景稳定工作。同时,LRC的器件可靠性经过长期验证,适合对稳定性要求高的应用。

五、典型应用场景

LR6302B36M的特性使其适配多类场景:

  1. 工业控制:PLC模块、传感器节点、工业相机供电(宽温、抗干扰);
  2. 车载电子:仪表盘、车载蓝牙、倒车雷达供电(宽温、保护功能);
  3. 低功耗物联网:电池供电的智能传感器、LoRa节点(低Iq、长续航);
  4. 高精度模拟电路:射频前端、音频放大器、ADC/DAC供电(低噪声、高PSRR);
  5. 消费电子:便携式医疗设备、智能手环辅助电源(小体积、保护功能)。

六、封装与应用注意事项

1. 常见封装

LRC通常提供SOT-23-3(小型表面贴装)、SOT-89-3(散热更好)等封装,适配不同PCB设计需求。

2. 应用注意事项

  • 输入/输出需并联0.1μF~1μF陶瓷电容(靠近器件引脚),稳定输出电压并抑制噪声;
  • 输入电压不得超过18V,避免器件损坏;
  • 若负载电流接近300mA,需考虑PCB散热(如增加铜箔面积),防止结温过高触发过热保护;
  • 输出电容建议使用低ESR陶瓷电容,提升纹波抑制效果。

LR6302B36M凭借其低功耗、低噪声、宽温宽压及全保护特性,成为中小功率稳定电源的高性价比选择,适用于对电源品质要求较高的各类应用。

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.
