Regulated voltage output.
Ground terminal.
No connect.
Output voltage adjust terminal. Output voltage setting is programmed with a resistor divider from
V_OUT to this input. A capacitor may also be added to this input to reduce output noise.
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.
