OM1905STM OM1912STM OM1915STM OM1905NTM OM1912NTM OM1915NTM ISOLATED HERMETIC FIXED VOLTAGE NEGATIVE REGULATORS APPROVED TO DESC DRAWINGS Three Terminal, Fixed Voltage, 1.5 Amp Precision Negative 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 7905, 7912, 7915 DESCRIPTION These three terminal negative regulators are supplied in a hermetically sealed metall 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 to ±1% of nominal voltage. Standard voltages are -5V, -12V, -15V. These units are ideally suited for Military applications where a hermetically sealed package is required.
