| OM7639SM OM7640SM OM7641SM SURFACE MOUNT POSITIVE VOLTAGE REGULATOR, 3-TERMINAL, FIXED VOLTAGE Isolated Hermetic Surface Mount Package 1.5 Amp, +5V, +12V, +15V Positive Voltage Regulators FEATURES * * * * * * * Small Hermetic Surface Mount Package Chip Isolated From 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 hermetic metal 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 output voltage. Standard voltages are 5V, 12V, and 15V. These units are ideally suited for Military applications where a hermetically sealed surface mount package is required.
