Austin Semiconductor, Inc.

PRELIMINARY SPECIFICATION

*Stresses greater than those listed under "Absolute Maximum

Ratings" may cause permanent damage to the device. This is

a stress rating only and functional operation of the device at

these or any other conditions above those indicated in the

operation section of this specification is not implied. Exposure

to absolute maximum rating conditions for extended periods

may affect reliability.

Operating Temperature Range ....................... -55C < Ta < +125C

Maximum Junction Temperature ......................................... +150C

Storage Temperature Range ........................... -65C < Ta < +150C

Lead Temperature (soldering for 10 sec) ............................ 300C

Input to Output Voltage Differential ............................+40V, -0.3V

Power Dissipation ........................................... Internally Limited

Output Short Circuit Duration..................................................10 sec

Lead Temperature (Soldering, 10 sec).......................................300°C

Thermal Resistance:

Theta JATO-03 Metal Can .........still air............186C/W

.......500LF/min air flow...... 64C/W

Theta JA 16Lead Gullwing ....still air............... 115C/W

.......500LF/min air flow....... 66C/W

Theta JC TO-03 Metal Can .....still air.............. 21C/W

Theta JC 16Lead Gullwing .....still air............... 3.4C/W

-(see note 3)

Package Weight:

16 Lead Cerpack Gullwing ................................ 380mg

3 Lead Metal Can ............................................... 950mg

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.
