GENERAL DESCRIPTION
The AS117 is an adjustable 3-terminal positive voltage
regulator capable of supplying in excess of .5A over a 1.2V to
37V output voltage range. It is exceptionally easy to use &
requires only 2 external resistors to set the output voltage.
Further, both line and load regulation are better than standard
fixed regulators.
In addition to higher performance than fixed regulators,
the AS117 offers full overload protection. Included on the chip
are current limit, thermal overload protection and safe area pro-
tection. All overload protection circuitry remains fully func-
tional even if the adjustment terminal is disconnected.
The AS117 is radiation tolerant to 100K Rads(Si) total
dose levels as tested by MIL-STD-883 Method 1019 Condition
A. The user is encouraged to contact ASI for acopy of current
radiation testing reports.
