DESCRIPTION
This three terminal positive 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.

Note 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.
Note 2:
Short Circuit protection is only assured up to V
