OM7608SC OM7610SC OM7609SC ISOLATED HERMETIC TO-258AA FIXED VOLTAGE REGULATORS Three Terminal, Fixed Voltage, 3.0 Amp Precision Negative Regulators In Hermetic JEDEC TO-258AA Package FEATURES • • • • • • Isolated Hermetic Package, JEDEC TO-258AA Outline Ouput Voltages: -5V, -12V And -15V Output Voltages Set Internally To ±2% (±1% Available) Built-In Thermal Overload Protection Short Circuit Current Limiting Product Is Available Screened To MIL-STD-883 DESCRIPTION These three terminal negative 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 ±1% available on request.
