Name and Function

1

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.
