DESCRIPTION
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.
