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 temperatur...
