<p><span>该稳压器的最大输出电流</span><span><span> </span>200mA<span> </span></span><span>，能够驱动车身控制模块、接线盒、仪表盘、天窗控制器、无钥匙进入控制器和传感器等负载。通过三个外部片选引脚可将输出电压设为</span><span><span> </span>0.8V</span><span>、</span><span>1.2V</span><span>、</span><span>1.5V</span><span>、</span><span>1.8V</span><span>、</span><span>2.5V</span><span>、</span><span>2.8V</span><span>、</span><span>3.3V<span> </span></span><span>或</span><span><span> </span>5V</span><span>，输出电压精度好于外部分压器，在标称电压的</span><span>±2%</span><span>范围内。</span></p>
<p><span>目前该产品共有两款。</span><span>L99VR01S<span> </span></span><span>采用标准</span><span><span> </span>SO-8<span> </span></span><span>封装，具有使能引脚和复位引脚，以及快速输出放电、欠压锁定</span><span><span> </span>(UVLO)</span><span>、热关断和短路保护等安全功能，禁用时静态电流降至</span><span><span> </span>1</span><span>μ</span><span>A</span><span>，工作温度范围</span><span><span> </span>-40°C<span> </span></span><span>至</span><span><span> </span>150°C</span><span>。</span></p>
<p><span>L99VR01J</span><span>采用</span><span><span> </span>PowerSSO-12</span><span>封装，比上一款增加短路限流设置、高温预警和输出过压状态指示功能，并内置一个可编程看门狗，用于验证主控微控制器操作是否正常。</span><span>L99VR01J<span> </span></span><span>的工作结温范围更宽，达到</span><span><span> </span>-40°C<span> </span></span><span>到</span><span><span> </span>175°C</span><span>。</span></p>
<p><span>通过在片上集成输出过压监测，新稳压器可以提供连续的负载保护。该诊断功能可以简化功能性安全相关应用的设计，帮助用户达到</span><span><span> </span>ISO 26262 ASIL</span><span>功能性安全标准的要求，如用户需要，提供相应的支持文档。</span></p>
<p><span>两款产品的输入电压范围是</span><span>2.15V</span><span>到</span><span>28V</span><span>，可直连汽车电瓶电压</span><span>VBAT</span><span>，或者连接在稳压电源的后面，调整稳压电源的输出电压。</span></p>
