LDO Plus
Analog Devices' LDO (Low-Dropout) Plus product portfolio provides additional functionality and features beyond basic linear regulator performance. The LDO Plus devices come with advanced functionalities such as voltage, current, and temperature monitoring that help to provide diagnostic information. Furthermore, features such as programmable current limit, active output discharge, or the ability to control an upstream supply make design with LDO Plus highly flexible.
