This pin is the positive side of the reference voltage for the device. With this pin it is possible to Kelvin-sense the
output voltage at the load.
This pin is the negative side of the reference voltage for the device. Ripple rejection can be improved by adding
a small bypass capacitor from the ADJUST pin to ground. The capacitor value should be selected so that:

SENSE leads of the LX8580A
This is the regulated power output of the device
This pin is the voltage supply pin for the control circuitry of the device. The current flow into this pin will be about
1% of the output current. Please refer to the electrical characteristics section of
the data sheet for dropout voltage for load conditions.
This is the collector of the power section of the LX8580A. The output load current is supplied through this pin.
For the device to regulate, the voltage at this pin must be between 0.1V and 0.8V greater than the output voltage
(Higher output current require higher voltages differences between V
