DESCRIPTION
These three terminal negative regulators are supplied in a hermetically sealed TO-3
metal 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% of nominal voltage. Standard voltages are -5V, -12V, -15V. These
units are ideally suited for Military applications where a hermetically sealed package
is required.
