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-on-
reset circuit. The first regulator can source 150mA, while the
second is capable of sourcing 300mA and has a power-on-
reset 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. .
