Texas Instruments  LP3996QSDX-1833/NOPB

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 × 3 mm package.
