Three Terminal, 3.3 Volt Positive Fixed
Low Dropout Voltage Regulator In
Hermetic JEDEC TO-257AA
and Surface Mount Packages
F E AT U R E S
• Similar To Industry Standard LT1086 -3.3
• Approved To DS C C Standardized Military Drawing Number 5962-98590
• Built In Thermal Overload Protection
• Short Circuit Current Limiting
• Available In Isolated Package
• Output Voltage Tolerance is Guaranteed To ±1%
• Guaranteed Dropout Voltage At Multiple Current Levels
DESCRIPTION
This 3.3 volt fixed voltage regulator is designed to provide 1.3A of current with a higher
efficiency than conventional voltage regulators. This device is designed to operate down to 1
volt input to output differential and the 1.5V dropout voltage is guaranteed at the maximum
output current. This device is ideally suited for those systems where high reliability, small size
and low weight are required. The isolated package simplifies the system assembly methods.

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 13 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.
2. Guaranteed by design, characterization or correlation to other tested parameters.
3. The • denotes the specifications which apply over the full operating temperature range.
