1 1 EN1 Enable Input for the First 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 Second 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. 1 N/A means not applicable. Rev.
