(COTS) COMMERCIAL OFF-THE-SHELF POSITIVE
FIXED VOLTAGE REGULATORS IN TO-257 PA C K-
Three Terminal, Fixed Voltage, 1.5 Amp
Precision Positive Regulators In Hermetic
JEDEC TO-257AA Package
FEATURES
• Isolated Hermetic Package, JEDEC TO-257AA Outline
• Output Voltages: 5V, 12V, 15V
• Output Voltages Set Internally ±2%
• Built-In Thermal Overload Protection
• Short Circuit Current Limiting
• Standard Off-The-Shelf
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 1.5 amps of output current.
These units feature internally trimmed output voltages to +/- 2% of nominal voltage.
Standard voltages are 5V, 12 V, and 15V. However, other voltages are available up to 24
volts. These units are ideally suited for Military applications where a hermetically sealed
package is required.
