Dc Voltage Regulator High Current

Dc Voltage Regulator High Current. The pnp transistor is used to stand off the high voltage while passing the current from the ina138 through to a ground referenced resistor. Voltage regulation in a switching regulator is achieved by the on and off action limiting the amount of current flow based on the varying line and load conditions.
