Regulated voltage output.
No connect.
No connect.
Ground terminal.
Reference bypass input. Connecting a 470pF to this input further reduces output noise.
No connect.
Shutdown control input. The regulator is fully enabled when a logic high is applied to this input.
The regulator is fully enabled when a logic high is applied to this input. The regulator enters shut-
down when a logic low is applied to this input. During shutdown, output voltage falls to zero and
supply current is reduced to 0.05A (typical).
Unregulated supply input.
