The LP5996 is a dual low dropout regulator. The first regulator can source 150mA, while the second is capable of sourcing 300mA.
The LP5996 provides 1.5% accuracy requiring an ultra low quiescent current of 35μA. Separate enable pins allow each output of the LP5996 to be shut down, drawing virtually zero current.
The LP5996 is designed to be stable with small footprint ceramic capacitors down to 1μF.
The LP5996 is available in fixed output voltages and comes in a 10 pin, 3mm x 3mm package.
