OM1905NKM OM1915NKM OM1912NKM HERMETIC TO-3 FIXED VOLTAGE NEGATIVE REGULATORS APPROVED TO DESC DRAWINGS Three Terminal, Fixed Voltage, 1.5 Amp Precision Negative Regulators In Hermetic JEDEC TO-3 Package FEATURES • • • • • • Output Voltages: -5V, -12V, -15V Output Voltages Set Internally to ±1% Built-In Thermal Overload Protection Short Circuit Current Limiting Similar To Industry Standards 7905, 7912, 7915 Hi-Rel Screening Available DESCRIPTION These three terminal negative regulators are supplied in a hermetically sealed TO-3 metal 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.
