Bias Input Voltage.
Bypass: Connect a capacitor to ground to reduce noise and
reduce ripple rejection.
Adjustable: Feedback input from external resistor divider.
Enable Input: Active High Input. Logic High = On;
Logic Low = Off; Do not leave floating.
Output of regulator.
Exposed heatsink pad connected to ground internally.
