Pin Description  
other or to any external signal, voltage, or  
ground. One or more of these pins may be  
connected internally.  
VSENSE (Pin 15):  
Sense pin for output  
voltage regulation. Connect VSENSE to the  
output voltage rail as close to the terminal of  
the output filter capacitor as possible.  
VFB (Pin 16): Feedback pin for external divider  
option. When using the external divider option  
(VS0=VS1=VS2= high) connect this pin to the  
center of the external divider. Set the divider  
such that VFB = 0.603V.  
VS0,VS1,VS2 (Pin 17,18,19): Output voltage  
select. VS0=pin19, VS1=pin18, VS2=pin17.  
Selects one of seven preset output voltages or  
choose external divider by connecting pins to  
logic high or low. Logic low is defined as VLOW  
0.4V. Logic high is defined as VHIGH 1.4V.  
Any level between these two values is  
indeterminate.  
Figure 2. Pin description, top view.  
VIN (Pin 1,2): Input voltage pin. Supplies  
power to the IC.  
Input GND: (Pin 3): Input power ground.  
Connect this pin to the ground terminal of the  
ENABLE (Pin 20): Output enable. Enable =  
logic high, disable = logic low. Logic low is  
defined as VLOW 0.2V. Logic high is defined  
as VHIGH 1.4V. Any level between these two  
values is indeterminate.  
input  
capacitor.  
Refer  
to  
Layout  
Recommendations for further details.  
Output GND: (Pin 4): Power ground. The  
output filter capacitor should be connected  
between this pin and VOUT. Refer to Layout  
recommendations for further detail.  
Bottom Thermal Pad: Device thermal pad to  
remove heat from package. Connect to PCB  
surface ground pad and PCB internal ground  
plane (see layout recommendations).  
VOUT (Pin 5,6,7): Regulated output voltage.  
NC (Pin 8,9,10,11,12,13,14): These pins  
should not be electrically connected to each
