| OM7800IH Series ISOLATED HERMETIC TO-257AA FIXED VOLTAGE REGULATORS 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 (Other Voltages Available) Output Voltages Set Internally To 1% or 2% Built-In Thermal Overload Protection Short Ciruit Current Limiting Product Is Available Screened To OM803 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 to 1% or 2% of nominal voltage. Standard voltages are 5V, 12V, and 15V. However, other voltages are available up to 24 volts. These units are ideally suited for Military applications where a hermetically sealed package is required.
