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.
Connect the midpoint of the voltage divider from VOUT1 to GND to set VOUT1.
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.
Connect the midpoint of the voltage divider from VOUT2 to GND to set VOUT2.
Regulated Output Voltage 3. Connect a 1 μF or greater output capacitor between VOUT3 and GND.
Connect the midpoint of the voltage divider from VOUT3 to GND to set VOUT3.
Regulator Input Supply for Output Voltage 3. Bypass VIN3 to GND with a 1 μF or greater capacitor.
Not connected internally.
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 EN3 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.
