Table 5. Pin Function Descriptions
Pin No. Mnemonic Description
1 EN1 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.
2 VBIAS Input Voltage Bias Supply. Bypass VBIAS to GND with a 1 µF or greater capacitor.
3 VIN1/VIN2 Regulator Input Supply for Output Voltage 1 and Output Voltage 2. Bypass VIN1/VIN2 to GND with a 1 µF or
greater capacitor.
4 VIN1/VIN2 Regulator Input Supply for Output Voltage 1 and Output Voltage 2. Bypass VIN1/VIN2 to GND with a 1 µF or
greater capacitor.
5 VOUT1 Regulated Output Voltage 1. Connect a 1 µF or greater output capacitor between VOUT1 and GND.
6 VOUT2 Regulated Output Voltage 2. Connect a 1 µF or greater output capacitor between VOUT2 and GND.
7 VOUT3 Regulated Output Voltage 3. Connect a 1 µF or greater output capacitor between VOUT3 and GND.
8 NC Not connected internally.
9 VIN3 Regulator Input Supply for Output Voltage 3. Bypass VIN3 to GND with a 1 µF or greater capacitor.
10 VIN3 Regulator Input Supply for Output Voltage 3. Bypass VIN3 to GND with a 1 µF or greater capacitor.
11 GND Ground Pin.
12 GND Ground Pin.
13 NC Not connected internally.
14 NC Not connected internally.
15 EN3 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.
16 EN2 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.
EP EP Exposed pad for enhanced thermal performance. Connect to copper ground plane.
