Description
Enable Input for Regulator 1. Drive EN1 high to turn on Regulator 1; drive it low to turn off Regulator 1. For
automatic startup, connect EN1 to VBIAS.
Input Voltage Bias Supply. Bypass VBIAS to GND with a 1 µF or greater capacitor.
Regulator Input Supply for Output Voltage 1 and Output Voltage 2. Bypass VIN1/VIN2 to GND with a 1 µF or
greater capacitor.
Regulator Input Supply for Output Voltage 1 and Output Voltage 2. Bypass VIN1/VIN2 to GND with a 1 µF or
greater capacitor.
Regulated Output Voltage 1. Connect a 1 µF or greater output capacitor between VOUT1 and GND.
Regulated Output Voltage 2. Connect a 1 µF or greater output capacitor between VOUT2 and GND.
Regulated Output Voltage 3. Connect a 1 µF or greater output capacitor between VOUT3 and GND.
Not connected internally.
Regulator Input Supply for Output Voltage 3. Bypass VIN3 to GND with a 1 µF or greater capacitor.
Regulator Input Supply for Output Voltage 3. Bypass VIN3 to GND with a 1 µF or greater capacitor.
Ground Pin.
Ground Pin.
Not connected internally.
Not connected internally.
Enable Input for Regulator 3. Drive EN3 high to turn on Regulator 3; drive it low to turn off Regulator 3. For
automatic startup, connect EN3 to VBIAS.
Enable Input for Regulator 2. Drive EN1 high to turn on Regulator 2; drive it low to turn off Regulator 2. For
automatic startup, connect EN2 to VBIAS.
Exposed pad for enhanced thermal performance. Connect to copper ground plane.
NOTES
1. NC = NO CONNECT.
2. CONNECT EXPOSED PAD TO GROUND PLANE.
