ISOLATED HERMETIC TO-257AA ADJUSTABLE
VOLTAGE REGULATORS
Three Terminal, Adjustable Voltage, 3.0 Amp
Precision Negative Regulators In Hermetic
JEDEC TO-257AA Package
FEATURES
• Isolated Hermetic Package, JEDEC TO-257AA Outline
• Reference Voltage Set Internally to ±2%
• Built-In Thermal Overload Protection
• Short Circuit Current Limiting
• Pin Out Identical To Plastic TO-220
• 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-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 3.0 amps of
output current. These units feature 2% initial voltage tolerance, with 1.0% load
regulation and .015% line regulation.
