OM1805STM OM1812STM OM1815STM OM1805NTM OM1812NTM OM1815NTM ISOLATED HERMETIC TO-257AA FIXED VOLTAGE REGULATORS APPROVED TO DESC DRAWINGS Three Terminal, Fixed Voltage, 1.5 Amp Precision Positive Regulators In Hermetic JEDEC TO-257AA Package FEATURES • • • • • • • Isolated Hermetic Package, JEDEC TO-257AA Outline Output Voltages: 5V, 12V, 15V Output Voltages Set Internally to ±1% Built-In Thermal Overload Protection Short Circuit Current Limiting Product Is Also Available In Non-Isolated Package Similar To Industry Standards 7805, 7812, 7815 DESCRIPTION These three terminal positive regulators are supplied in a hermetically sealed metal package whose outline is similar to the industry standard TO-220 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 1.5 amps of output current. These units feature internally trimmed output voltages ±1% of nominal voltage. These units are ideally suited for Military applications where a hermetically sealed package is required.
