The LDO40L is a 400 mA LDO regulator, designed for being used in severe automotive environments.
Low quiescent current makes it suitable for applications permanently connected to battery. This feature is especially critical when electronic modules remain in active mode when ignition is off.
The LDO40L embeds protection functions, such as: current limit and thermal shutdown.
The extended input voltage range, low drop voltage and low quiescent current features make it suitable also for low power industrial and consumer applications.主要特性
