ISOLATED HERMETIC TO-257AA
ADJUSTABLE VOLTAGE REGULATOR
4 11 R4
Supersedes 1 07 R3
FEATURES
• Isolated Hermetic Package, JEDEC TO-257AA Outline
• Adjustable Output Voltage
• Eliminates Stocking Fixed Voltages
• Built-In Thermal Overload Protection
• Short Circuit Current Limiting
• Product Is Available Screened To MIL-STD -883

DESCRIPTION
This three terminal negative regulator is 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 1.0 amp of
output current. This unit features output voltages that can be trimmed using external
resistors, from -1.2 volts to -37 volts.
