DESCRIPTION
The LP3996 is a dual low dropout regulator with
Thermal Shutdown Protection
power-on-reset circuit. 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.
