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 ±1% or ±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.
