OM7662SC OM7663SC OM7664SC ISOLATED HERMETIC TO-258AA FIXED POSITIVE VOLTAGE REGULATORS Three Terminal, Fixed Positive Voltage, 3.0 Amp Precision Positive Regulator In Hermetic JEDEC TO-258AA Package FEATURES * * * * * * Isolated Hermetic Package. JEDEC TO-258AA Outline Ouput Voltages: 5V, 12V And 15V (Other Voltages Available) Output Volatges Set Internally To 2% (1% Available) Built-In Thermal Overload Protection Short Circuit Current Limiting Product Is Available Hi-Rel Screened DESCRIPTION These three terminal positive regulators are supplied in a hermetically sealed metal package whose outline is similar to the industry standard TO-247 plastic package. All protective features are designed into the circuit, including thermal shutdown, current limiting and safe-area control. With heat sinking, they can deliver over 3.0 amps of output current. These units feature 2% initial voltage tolerance, with 0.3% load regulation and .01% line regulation.
