3.1 Regulated Output Voltage (V_OUT)
Regulated voltage output.
3.2 Ground (GND)
Ground terminal.
3.3 Reference Bypass (BYPASS)
Reference bypass input. Connecting a 470 pF to this
input further reduces output noise.
3.4 Out-of-Regulation Flag (ERROR)
Out-of-regulation flag (open-drain output). This output
goes low when V_OUT 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 this input. The regulator
enters shutdown when a logic-low is applied to this
input. During shutdown, the output voltage falls to zero
and the supply current is reduced to 0.05 µA (typical).
3.6 Unregulated Supply (V_IN)
Unregulated supply input.
