FEATURES
DESCRIPTION
The LP3996-Q1 is a dual low dropout regulator with
2
2 LDO Outputs with Independent Enable
power-on-reset circuit. The first regulator can source
1.5% Accuracy at Room Temperature, 3% Over
150 mA, while the second is capable of sourcing 300
Temperature
mA and has a power-on-reset function included.
Power-On-Reset Function with Adjustable
The LP3996-Q1 provides 1.5% accuracy requiring an
Delay
ultra low quiescent current of 35 µA. Separate enable
Thermal Shutdown Protection
pins allow each output of the LP3996-Q1 to be shut
down, drawing virtually zero current.
Stable with Ceramic Capacitors
Qualified for Automotive Applications
The device is designed to be stable with small
footprint ceramic capacitors down to 1 µF. An
AEC-Q100 Test Guidance with the Following
external capacitor may be used to set the POR delay
