Output voltage adjust terminal. Output voltage setting is programmed with a resistor divider from
V
Reference bypass input. Connecting a 470pF to this input further reduces output noise.
Shutdown control input. The regulator is fully enabled when a logic high is applied to this input.
The regulator enters shutdown when a logic low is applied to this input. During shutdown, output
voltage falls to zero and supply current is reduced to 0.05µA (typical).
No connect.
Unregulated supply input.
OUT
to this input. A capacitor may also be added to this input to reduce output noise.
