LDO Plus

Analog Devices’ LDO Plus devices provide additional functionality and features beyond the basic linear regulator performance. Functionality may include voltage, current, and temperature monitoring; diagnostic information; and features such as programmable current limit, active output discharge, or the ability to control an upstream supply powering the LDO.
