3.1 Regulated Output Voltage (VOUT)
VOUT is a regulated voltage output.
3.2 Ground (GND)
Ground terminal.
3.3 Reference Bypass (BYPASS)
Reference bypass input. Connect a 470 pF to the
BYPASS input to further reduce output noise.
3.4 Out-of-Regulation Flag (ERROR)
Out-of-Regulation Flag (open-drain output). ERROR
goes low when VOUT is out-of-tolerance by
approximately – 5%.
3.5 Shutdown Control (SHDN)
Shutdown control input. The regulator is fully enabled
when a logic-high is applied to SHDN. 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 0.05 µA (typical).
3.6 Unregulated Supply (VIN)
VIN is an unregulated supply input.
