Dual isolated 5V low drop linear voltage regulator

Download Databrief

L5050x is a low dropout linear 5 V regulator suitable for automotive application, available in single (L5050S) or dual isolated (L5050SD) linear output voltage in a SO-8 package. The LDO delivers up to 50 mA (2x50 mA for the dual version) of load current, and consumes as low as 50 μA (per each Output) of quiescent current in light load condition. High output voltage accuracy (2%) is kept over wide temperature range line and load variation. Enable feature (two Enables for the dual version) allow enabling or disabling each output. The maximum input voltage is 40 V. The regulator output current is internally limited and the device is protected against short circuit, overload and over temperature conditions. In addition, only low value ceramic capacitor on output is required for stability.

Key Features
