1
SW
switching pin.
2
GND
Ground.
3
FB
Regulation Feedback Input. Connect to an external resistive voltage divider from the
output to FB to set the output voltage.
4
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 LP6226 into low current shutdown mode.
