THREE-TERMINAL ADJUSTABLE
OUTPUT POSITIVE VOLTAGE REGULATORS
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 IL317 serve a wide variety of applications to
make a programmable output regulator, or by connecting a
fixed resistor between the adjustment and output, the IL317 series can be used as a precision current
requlator.
