LP3996 Dual Linear
Regulator with 300mA and 150mA Outputs and Power-On-Reset
General Description
The LP3996 is a dual low dropout
regulator with power-onreset circuit. The first
regulator can source 150mA, while the second is capable of sourcing 300mA and has a power-onreset function included. The LP3996 provides 1.5% accuracy requiring an ultra low quiescent current of 35µA. Separate enable pins allow each output of the LP3996 to be shut down, drawing virtually zero current. The LP3996 is designed to be stable with small footprint ceramic capacitors down to 1µF. An external capacitor may be used to set the POR delay time as required. The LP3996 is available in fixed output voltages and comes in a 10 pin, 3mm x 3mm, LLP package. .
