15V_AT_5A_WITH_PROTECTION
External boost transistor is used with National LM340T-15 regulator to boost output current capability to 5A without affecting such features as short-circuit current limiting and thermal shutdown. Short-circuit current is held to 5,5A. Heatsink for Q1 should have at least 4 times capacity of heatsink for IC.- Linear Applications, Vol. 2, National Semiconductor, Santa Clara, CA, 1976, AN-103,p3-4.
