Regulated voltage output.

Ground terminal.

No connect.

Reference bypass input. Connecting a 470pF to this input further reduces output noise.

Out-of-Regulation Flag. (Open drain output). This output goes low when VOUT is out-of-tolerance

by approximately – 5%.

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.
