The first regulator can source • Stable with Ceramic Capacitors 150 mA, while the second is capable of sourcing 300 mA and has a power-on-reset function included. KEY SPECIFICATIONS The LP3996 provides 1.5% accuracy requiring an • Input Voltage Range 2.0V to 6.0V ultra low quiescent current of 35 µA. Separate enable • Low Dropout Voltage 210 mV at 300 mA pins allow each output of the LP3996 to be shut down, drawing virtually zero current. • Ultra-Low IQ (Enabled) 35 µA • Virtually Zero IQ (Disabled) <10 nA The LP3996 is designed to be stable with small footprint ceramic capacitors down to 1 µF. An • Package Available in Lead-Free Option external capacitor may be used to set the POR delay 10-pin 3 mm x 3 mm time as required. The LP3996 is available in fixed output voltages and comes in a 10-pin, 3 mm x 3 mm package.
