7.5 AMP LOW DROPOUT POSITIVE ADJUSTABLE  
REGULATOR APPROVED TO DESC DRAWING 5962-89520  
Three Terminal, Positive Adjustable  
Low Dropout Voltage Regulator In  
Hermetic JEDEC TO-258AA Package  
FEATURES  
• Similar To Industry Standard LT1083  
• Approved To DESC Standardized Military Drawing Number 5962-8952001Y  
• Adjustable Output Voltage  
• Built In Thermal Overload Protection  
• Short Circuit Current Limiting  
• Available In Isolated Package  
• Maximum Output Voltage Tolerance is Guaranteed To ±1%  
• Guaranteed Dropout Voltage At Multiple Current Levels  
• Product Also Available in Non-Isolated Package  
DESCRIPTION  
This three terminal positive adjustable voltage regulator is designed to provide 7.5A  
with higher efficiency than conventional voltage regulators. This device is designed  
to operate down to 1 volt input to output differential and the dropout voltage is fully  
specified as a function of load current. Supplied in easy-to-use hermetic TO-258  
package, this device is ideally suited for Military applications where small size and  
high reliability is required.

Notes:  
1. Line and Load Regulation are measured at a constant junction temperature using a low duty cycle pulse technique.  
Although power dissipation is internally limited, regulation is guaranteed up to the maximum power dissipation of 60 W.  
Power dissipation is determined by the input/output differential voltage and the output current. Guaranteed maximum  
power dissipation will not be available over the full input/output voltage range.  
3.3  
2. Guaranteed by design, characterization or correlation to other tested parameters.  
3. The • denotes the specifications which apply over the full operating temperature range.
