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 7805, 7812, 7815
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
±1% of nominal voltage. These units are ideally suited for Military applications where
a hermetically sealed package is required.
