Abstract
A switching regulator arrangement utilizes internal capacitors rather than external capacitors for driving output power transistors. Low-dropout linear voltage regulators together with a dip compensation circuit provide an intermediate supply voltage for driving power transistors under circumstances in which a supply voltage is greater than a gate drive voltage of the power transistor, allowing for a more efficient absorption of transient current.
