Description
L5050 is a 5 V low dropout linear voltage regulator suitable for automotive
applications, 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 DC load current and consumes as low as 5 μA (per each output in
L5050SD) of quiescent current with device disabled. High output voltage accuracy (±
2%) is kept over wide temperature range, line and load variation. The L5050S is able
to deliver up to 100 mA (as pulsed current) and L5050SD up to 2x100 mA (as pulsed
current); duration of current is linked to thermal settings (such as PCB type, ambient
temperature). Enable features (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.
