1.5 AMP LOW DROPOUT POSITIVE ADJUSTABLE REGULATOR APPROVED TO DESC DRAWING 5962-89981
Three Terminal, Positive Adjustable Low Dropout Voltage Regulator In Hermetic Packages
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% 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.

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 15 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.
