DESCRIPTION
These three terminal negative regulators are supplied in a hermetically sealed
metal package whose outline is similar to the industry standard TO-220 plastic pack-
age. 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.
