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. .
