Shutdown Input: Disables the regulator when is connected to GND or to positive
voltage less than 0.6 V
Ground Pin: Internally connected to the die attach flag to decrease the total thermal
resistance and increase the package ability to dissipate power.
Bypass Pin: Bypass with 0.1 µF to improve the V
