LDL40 200mA Low-Dropout (LDO) Voltage Regulator

STMicroelectronics LDL40 200mA Low-Dropout (LDO) Voltage Regulator is a high-accuracy voltage regulator designed to be directly connected to a car battery in automotive applications or a generic battery used in industrial applications. Extended input voltage up to 40V 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.
