*EP = Exposed pad.
Regulator Enable/Undervoltage-
Lockout Level (EN/UVLO)
The device features an EN/UVLO input. For normal
operation, a shunt should be installed across pins 1-2 on
jumper JU1. To disable the output, install a shunt across
pins 2-3 on JU1 and the EN/UVLO pin is pulled to GND.
See Table 1 for JU1 settings.
Setting the Undervoltage-Lockout Level
The device offers an adjustable input undervoltage-lock-
out level. Set the voltage at which the device turns on with
a resistive voltage-divider connected from VIN to GND.
Connect the center node of the divider to EN/UVLO.
Choose R1 to be 3.3MΩ and then calculate R2 as follows:
