(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, 12V, 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.

Notes:
1.Load and Line Regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used. Changes in output voltage due to heating effects must be taken into account separately.
2.Short Circuit protection is only assured up to VIN = 35V.
3.If not tested, shall be guaranteed to the specified limits.
The • denotes the specifications which apply over the full operating temperature range.
