Description

General part information

LP3996-Q1 Series

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.
