NAME

DESCRIPTION

1

VIN

Supply Voltage/LDO Input. Connect a 1µF capacitor to GND.

2

GND

GND is the connection to system ground. Connect to PCB Ground plane.

3

EN2

LDO2 Enable pin. Enable = High, Disable = Low. A 100k resistor should be connected between EN2 and the control voltage

rail. Do NOT leave it floating.

4

EN1

LDO1 Enable pin. Enable = High, Disable = Low. A 100k resistor should be connected between EN1 and the control voltage

rail. Do NOT leave it floating.

5VOUT2

LDO2 Output. Connect capacitor with a value from 1µF to 4.7µF to GND (1µF recommended).

6

VOUT1

LDO1 Output. Connect capacitor with a value from 1µF to 4.7µF to GND (1µF recommended).
