NC
No Connector.
2
FB
Regulation Feedback Input. Connect to an external resistive voltage divider from the
output to FB to set the output voltage.
3
EN
Regulator ON/OFF Control Input. A logic high input(VEN>1.4V) turns on the regulator. A
logic low input(VEN<0.4V) puts the LP6230B into low current shutdown mode.
