DESCRIPTION
The LP5996 is a dual low dropout regulator. The first
regulator 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 package.

Function
Voltage Supply Input. Connect a 1µF capacitor between this pin and GND.
Enable Input to Regulator 1. Active high input.
High = On. Low = OFF.
Enable Input to Regulator 2. Active high input.
High = On. Low = OFF.
Internal Voltage Reference Bypass. Connect a 10nF capacitor from this pin to GND to reduce noise
and improve line transient and PSRR.
This pin may be left open.
No Connection. Do not connect to any other pin.
Common Ground pin. Connect externally to exposed pad.
No Connection. Do not connect to any other pin.
No Connection. Do not connect to any other pin.
Output of Regulator 2. 300mA maximum current output. Connect a 1µF capacitor between this pin to
GND.
Output of Regulator 1. 150mA maximum current output. Connect a 1µF capacitor between this pin to
GND.
Common Ground. Connect to Pin 6.
