SHDN
Shutdown Input: Disables the
regulator when is connected to GND
or to positive voltage less than 0.6V
2
GND
Ground Pin: Internally connected to
the die attach flag to decrease the
total thermal resistance and increase
the package ability to dissipate
power.
3
Bypass Bypass Pin: Bypass with 0.1
µF to
improve the Vref thermal noise
performances.
