DESCRIPTION
This three terminal negative regulator is supplied in a hermetically sealed surface
mount package. All protective features are designed into the circuit, including thermal
shutdown, current limiting and safe-area control. With heat sinking, they can deliver
1.0 amp of output current. This unit features internally trimmed voltages to ±2% of
nominal voltage. Standard voltages are -5V, -12V and -15V. These units are ideally
suited for Military applications where a hermetic surface mount package is required.
