output voltage controlled comparing portion internal reference driving pass transistor accordingly. control loop stability depends output capacitor load current, chip temperature poles/zeros introduced integrated circuit. ensure stable operation, output capacitor's capacitance equivalent series resistor requirements given table "Functional Range" Page have maintained. details also typical performance graph "Output Capacitor Series Resistor ESR(CQ) versus Output Current Page output capacitor also buffer load steps should sized according application's needs. input capacitor strongly recommended compensate line influences. Connect capacitors close component's terminals. protection circuitry prevents well application from destruction case catastrophic events. These safeguards contain output current limitation, reverse polarity protection well thermal shutdown case overtemperature. avoid excessive power dissipation that could never handled pass element package, maximum output current decreased input voltages above overtemperature shutdown circuit prevents from immediate destruction under fault conditions (e.g. output continuously short-circuited) switching power stage. After chip cooled down, regulator restarts. This leads oscillatory behaviour output voltage until fault removed. However, junction temperatures above outside maximum ratings therefore significantly reduce IC's lifetime. TLE42994 allows negative supply voltage. this fault condition, small currents flowing into increasing junction temperature. This considered thermal design, respecting that thermal protection circuit operating during reverse polarity conditions.
