LP5996
Dual Linear Regulator with 300mA and 150mA Outputs
General Description
The LP5996 is a dual low dropout regulator. The first regu-
lator can source 150mA, while the second is capable of
sourcing 300mA.
The LP5996 provides 1.5% accuracy requiring an ultra low
quiescent current of 35µA. Separate enable pins allow each
output of the LP5996 to be shut down, drawing virtually zero
current.
The LP5996 is designed to be stable with small footprint
ceramic capacitors down to 1µF.
The LP5996 is available in fixed output voltages and comes
in a 10 pin, 3mm x 3mm, LLP package. .
