EN
Enable input. With EN higher than 1.2 V the device in ON and with EN lower
than 0.4 V the device is OFF (ST1S40Ixx).
35
FB
Feedback input. Connecting the output voltage directly to this pin the output
voltage is regulated at 0.8 V. To have higher regulated voltages an external
resistor divider is required from Vout to the FB pin.
