The Vision 4B) DESCRIPTION The 78H12A positive 3 terminal fixed linear voltage regulator is capable of delivering a conti- nous load current in excess of 5 amperes at a nominal regulated output voltage of 12 volts. The 78H12A has built-in protection features such as output short circuit current limiting, thermal overload and safe operating area protection. If external conditions exceed the ‘78H12A's capabilities (see absolute maximums), the device temporarily shuts down protecting itself and the load circuit until the fault is removed. This feature eliminates costly addi- tional protection circuitry as well as overly conservative heat sinks typical of discrete high current voltage regulator designs. The 2 lead hermetic TO-204MA package, (formerly called . 10-3), provides up to 50 watts of internal power dissipation.
