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 V
by approximately – 5%.
No connect.
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).
Unregulated supply input.
