1.2.3. Voltage Regulators with Clamping Capability

There are voltage regulators on the market that clamp the output to GND in the event of a fault condition. When choosing the voltage regulator, ensure that this clamping feature can be disabled. Group 2 can be clamped only if it is clamped with the same control signal as Group 3. Otherwise, make sure that regulators in Group 1 and Group 2 do not have this option enabled.
