When both V
pin) the start-up phase takes place. Otherwise the SS pin is internally shorted to GND. At
start-up, a ramp is generated charging the external capacitor C
generator. The initial value for this current is 35 µA and charges the capacitor up to 0.5 V.
After that it becomes 10 µA until the final charge value of approximately 4 V (see
