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 protection. All overload protection circuitry remains fully functional 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.

Austin Semiconductor, Inc. TYPICAL APPLICATIONS
Besides replacing fixed regulators, the AS117 is useful in a wide variety of other applications. Since the regulator is "Floating" and sees only the input-to-output differential voltage, supplies of several hundred volts can be regulated as long as the maximum input to output differential is not exceeded, (i.e., avoid short circuiting the output). Also it makes an especially simple adjustable switching regulator, a programmable output regulator, or by connecting a fixed resistor between the adjustment pin & the output pin, the AS117 can be used as a precision current regulator. Supplies with electronic shutdown can be achieved by clamping the adjustment terminal to ground which programs the output to 1.2V where most loads draw little current. Normally no capacitors are needed unless the device is situated more than 6 inches from the input filter capacitors in which case an input bypass is needed. An optional output capacitor can be added to improve transient response. The adjustment terminal can be bypassed to achieve very high ripple rejection ratios which are difficult to achieve with standard 3-terminal regulators.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is functional , but do not guarantee specific performance limits. For guaranteed Specs & Test conditions, see Electrical Characteristics section. Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by Tjmax(max Junction temp), ThetaJA (package junction to ambient thermal resistance), and TA(ambient temp). The maximum allowable power dissipation at any temperature is Pdmax (Tjmax - TA)/ThetaJA or the number given in the Absolute Maximum Rating, whichever is lower. Note 3: For the Ceramic 16lead gullwing, device to function properly, the "OUTPUT" and "OUTPUT/SENSE" pins must be connected on the users printed circuit board.
