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 鹵1%
Guaranteed Dropout Voltage At Multiple Current Levels
TO-257 Available in Isolated and Non-Isolated Packages
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.
