Features
1) 13.3V (external transistor required), 12V, 10V, and
5.6V outputs are built in (one output for each volt-
age).
2) Output current limit circuit protects the IC against
short-circuiting damage.
3) Thermal protection circuit prevents heat damage to
the IC.
4) Compact SIP-M12 package allows a large power dis-
sipation.
