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.
