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 0.05µA (typical).

Unregulated supply input.
