【应用】日清纺车规级LDO用于汽车挡位执行器，工作温度-40~125℃，功耗低至0.1μA
汽车换挡器分为传统换挡器和电子换挡器两种。传统的换挡器是通过操作挡杆，依赖拉索来控制变速箱。随着汽车越来越深的智能化、电子化，电子换挡器越来越成为主流。电子换挡器是通过CAN来传输换挡信号给变速箱执行单元，挡位执行器接收换挡信号来执行换挡操作。电子换挡器和挡位执行器配套使用，整车用量1：1。
挡位执行器框图如图1所示。
图1 挡位执行器框图
挡位执行器应用于变速箱附近，在换挡期间会有瞬间的温升，因此要求挡位执行器所用物料均需满足高温要求，工作温度达125℃。针对电源模块部分，推荐NISSHINBO R1518J501B-T1-KE，其典型应用如图2所示。
图2 R1518J501B-T1-KE典型应用
NISSHINBO R1518J501B-T1-KE具有如下特性：
1.满足AEC-Q100认证，适用于汽车挡位执行器。
2.工作温度范围：-40~125℃，满足挡位执行器高温需求。
3.功耗低：待机模式下典型值0.1μA。
