| OM7629NM OM7630NM OM7631NM HERMETIC SURFACE MOUNT FIXED VOLTAGE POSITIVE REGULATORS Three Terminal, Fixed Voltage, 1.5 Amp Precision Positive Regulators In Hermetic Surface Mount Package FEATURES * * * * * * Hermetic Surface Mount Package Output Voltages: +5V, +12V, +15V Output Voltages Set Internally To 1% 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 surface mount 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, and +15V. These units are ideally suited for Military applications where a hermetic surface mount package is required.
