TECHNICAL DATA
THREE-TERMINAL ADJUSTABLE
OUTPUT POSITIVE VOLTAGE REGULATORS
IL317
The IL317 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 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.

Since IADJ is controlled to less then 100 mA, the error
associated with this term is negligible in most
applications.
