ISOLATED HERMETIC TO-257AA
ADJUSTABLE VOLTAGE REGULATOR
4 11 R4
Supersedes 1 07 R3
FEATURES
• Isolated Hermetic Package, JEDEC TO-257AA Outline
• Reference Voltages Set 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 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 3.0 amps of
output current. These units feature 2% initial voltage tolerance, 0.3% load regulation
and 0.01% line regulation.
