ISOLATED HERMETIC TO-258AA FIXED
POSITIVE VOLTAGE REGULATORS
FEATURES
Isolated Hermetic Package. JEDEC TO-258AA Outline
Ouput Voltages: 5V, 12V And 15V (Other Voltages Available)
Output Volatges Set Internally To 2% (1% Available)
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 metal
package whose outline is similar to the industry standard TO-247 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 3.0 amps of
output current. These units feature 2% initial voltage tolerance, with 0.3% load
regulation and .01% line regulation.
