1 08 R3
Supersedes 4 11 R2
FEATURES
• Similar To Industry Standard LT1086
• Approved To DESC Standardized Military Drawing Number 5962-89981
• Adjustable Output Voltage
• Built In Thermal Overload Protection
• Short Circuit Current Limiting
• Maximum Output Voltage Tolerance is Guaranteed To ±1%

DESCRIPTION
This three terminal positive adjustable voltage regulator is designed to provide 1.5A
with higher efficiency than conventional voltage regulators. This device is designed
to operate to 1 Volt input to output differential and the dropout voltage is specified as
a function of load current. Supplied in easy-to-use hermetic TO-257, TO-3 and
TO-39 packages, this device is ideally suited for Military applications where small size
and high reliability is required.
