Also, output capacitor shall sized buffer load transients. input capacitor recommended buffer line influences. Connect capacitors close terminals. Protection circuitry prevent well application from destruction case catastrophic events. These safeguards contain output current limitation, reverse polarity protection well thermal shutdown case overtemperature. order avoid excessive power dissipation that could never handled pass element package, maximum output current decreased high input voltages. overtemperature protection circuit prevents from immediate destruction under fault conditions output continuously short-circuited) reducing output current. thermal balance below junction temperature established. Please note that junction temperature above outside maximum ratings reduces lifetime. TLE4250-2 allows negative supply voltage. However, several small currents flowing into details electrical characteristics table typical performance graphs. thermal protection circuit operating during reverse polarity condition.
