DESCRIPTION

The LP3996-Q1 is a dual low dropout regulator with

power-on-reset circuit. The first regulator can source 150 mA, while the second is capable of sourcing 300

mA and has a power-on-reset function included.

The LP3996-Q1 provides 1.5% accuracy requiring an

ultra low quiescent current of 35 μA. Separate enable

pins allow each output of the LP3996-Q1 to be shut

down, drawing virtually zero current.

The device is designed to be stable with small

footprint ceramic capacitors down to 1 μF. An

external capacitor may be used to set the POR delay

time as required.

The LP3996-Q1 is available in fixed output voltages

and comes in a 10-pin, 3 mm x 3 mm package.
