Description
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.
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.
Ground Pin.
Adjust Pin for VOUT2. A resistor divider from VOUT2 to ADJ2 sets the output
voltage.
Sense Pin for VOUT2.
Regulated Output Voltage. Connect an 1 µF or greater output capacitor between
VOUT2 and GND.
Regulator Input Supply. Bypass VIN to GND with a 1 µF or greater capacitor.
Regulated Output Voltage. Connect 1 µF or greater output capacitor between
VOUT1 and GND.
Adjust Pin for VOUT1. A resistor divider from VOUT1 to ADJ1 sets the output
voltage.
Sense Pin for VOUT1.
The exposed paddle must be connected to ground.
