THREE-TERMINAL ADJUSTABLE OUTPUT POSITIVE VOLTAGE REGULATORS
The EP1017 are adjustable 3-terminal positive voltage regulators capable of supplying in excess of 1.5A over an output voltage range of 1.2 to 37V. These voltage regulators are exceptionally easy to use and require only two external resistors to set the output voltage. Further, they employ internal current limiting. Thermal shutdown and safe area compensation, making them essentially blow-out proof.
