I have trouble understanding the point of the diodes? When you are in sample mode there is Vin voltage over the capacitor, is this correct? Are those diodes there to create a "voltage-protection". +- 0.7 V? Or is it to maintain the feedback when in HOLD mode? The datasheet: https://www.ti.com/lit/ds/symlink/lf198-n.pdf Thank you!
