Extended input voltage up to 40 V makes the device able to support a load dump transient, which is typical in automotive systems. Ultra-low quiescent current at light load increases the battery operation lifetime in always-on-standby systems. The device is stabilized with a small ceramic capacitor on the input and output. An enable logic control function puts the LDL40 in shutdown mode allowing a total current consumption lower than 0.3 µA. Thermal protection is also included. The device is available in automotive grade in a very small footprint DFN package with wettable flanks, allowing the maximum space saving in the PCB (printed circuit board) design and AOI (automated optical inspection).
