HT317ARDZ

HT317A THREE-TERMINAL ADJUSTABLE OUTPUT POSITIVE VOLTAGE REGULATORS The HT317A is adjustable 3-terminal positive voltage regulator capable of supplying in excess of 1.5 A over an output voltage range of 1.2 V to 37 V. These voltage regulator is exceptionally easy to use and require only two external resistors to set the output voltage. Further, it employ internal current limiting, thermal shutdown and safe area compensation, making them essentially blow-out proof. The HT317A serve a wide variety of applications to make a programmable output regulator, or by connecting a fixed resistor between the adjustment and output, the HT317A series can be used as a precision current requlator.
