ABSTRACT:
A voltage regulator circuit having a series device external to an integrated circuit voltage regulator. The external series device provides a voltage drop prior to the voltage being input to the voltage regulator during high power applications. Depending on the power level, low or high, one of two transistors will be activated. For low power applications, a transistor attached directly to the input voltage is active and the external series device is bypassed. For high power applications, the external series device provides a voltage drop prior to the input voltage reaching the second transistor thereby lowering the power to be dissipated by the integrated circuit.
