Isolated Hermetic Package, JEDEC TO-258AA Outline
Ouput Voltages: -5V, -12V And -15V
Output Voltages Set Internally To ±2% (±1% Available)
Built-In Thermal Overload Protection
Short Circuit Current Limiting
Product Is Available Screened To MIL-STD-883
DESCRIPTION
These three terminal negative 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 ±1% available
on request.
