Description

1

1

EN1

Enable Input for the Second Regulator. Drive EN1 high to turn on Regulator 1 and

drive EN1 low to turn off Regulator 1. For automatic startup, connect EN1 to VIN.

2

2

EN2

Enable Input for the First Regulator. Drive EN2 high to turn on Regulator 2 and drive

EN2 low to turn off Regulator 2. For automatic startup, connect EN2 to VIN.

3

3

GND

Ground Pin.

N/A1

4

ADJ2

Adjust Pin for VOUT2. A resistor divider from VOUT2 to ADJ2 sets the output

voltage.

4

N/A1

SENSE2

Sense Pin for VOUT2.

5

5

VOUT2

Regulated Output Voltage. Connect an 1 µF or greater output capacitor between

VOUT2 and GND.

6

6

VIN

Regulator Input Supply. Bypass VIN to GND with a 1 µF or greater capacitor.

7

7

VOUT1

Regulated Output Voltage. Connect 1 µF or greater output capacitor between

VOUT1 and GND.

N/A1

8

ADJ1

Adjust Pin for VOUT1. A resistor divider from VOUT1 to ADJ1 sets the output

voltage.

8

N/A1

SENSE1

Sense Pin for VOUT1.

EPAD

The exposed paddle must be connected to ground.
