AS117 RAD-TOL

Rev. 1.1 06/05

Austin Semiconductor, Inc.

PRELIMINARY SPECIFICATION

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.

FEATURES

• Guaranteed 0.5A Output Current

• Radiation Guaranteed to 100K RADS TID

• Adjustable output down to 1.2V

• Current Limit constant over temperature

• Output is short circuit protected

• 80Db Ripple Rejection
