current of 250 mA with PDC = 0. Any additional load current requirement will be supplied
by the PNP transistor, up to its current limit. If the load current continues to rise, I
increase above the selected PDC threshold (to a maximum of 250 mA).
For a fast ramping load current, V1 will deliver the required load current (to a maximum of
250 mA) until the PNP transistor has switched on. Once the transistor has been activated,
V1 will deliver 85 mA (PDC = 0) with the transistor contributing the balance of the load
current (see
