TLE4254 electrical characteristics data sheet 8 rev. 1.2, 2009-11-18 5 electrical characteristics 5.1 tracking regulator the output voltage v q is controlled by comparing it to the voltage applied at pin adj/en and driving a pnp pass transistor accordingly. th e control loop stability depe nds on the outpu t capacitor c q , the load current, the chip temperature and the poles/zeros introduced by the integrated circuit and the load. to ensure stable operation, the output capacitor?s capacitance and its equivalent series resistor esr requirements given in the table ?functional range? have to be maintained. for details see also t he typical performance graph ?output capacitor series resistor esr cq vs. output current i q ?. also, the output capacitor shall be sized to buffer load transients. an input capacitor c i is strongly recommended to buffer line influen ces. connect the capacitors close to the ic terminals. protection circuitry prevent the ic as well as the application fr om destruction in case of catastrophic events. these safeguards contain output curr ent limitation, reverse polarity protection as well as thermal shutdown in case of overtemperature. in order to avoid excessive power dissipation that coul d never be handled by the pass element and the package, the maximum output current is de creased at high input voltages. the overtemperature protection circuit prevents the ic from immediate destruction under fault conditions (e. g. output continuously short-circuited) by reducing the output current. a thermal balance below 200 c junction temperature is established. please note that a junction temperature above 150 c is outside the maximum ratings and reduces the ic lifetime. the TLE4254 allows a negative supply voltage. however, se veral small currents are flowing into the ic increasing its junction temperature. th is has to be considered for the thermal des ign, respecting that the thermal protection circuit is not operating during reverse polarity condition. table 1 electrical characteristics tracking regulator v i = 13.5 v; v adj/en 2.0 v; v fb = v q (version ga / ej a); -40 c t j 150 c; c q = 1 f; all voltages with respect to grou nd (unless other wise specified). pos. parameter symbol limit values unit test condition min. typ. max. 5.1.1 output voltage tracking accuracy ? v q = v en/adj - v q ? v q -5 ? 5 mv 8 v v i 18 v; 0.1 ma i q 60 ma; v adj/en = 5 v 5.1.2 -10 ? 10 mv 5.5 v v i 26 v; 0.1 ma i q 60 ma; v adj/en = 5 v 5.1.3 -10 ? 10 mv 5.5 v v i 32 v; 0.1 ma i q 30 ma; v adj/en = 5 v 5.1.4 load regulation steady-state |d v q,load |? 1 10 mv i q = 0.1 ma to 70 ma; v adj/en = 5 v 5.1.5 line regulation steady-state |d v q,line |? 1 10 mv v i = 5.5 v to 32 v; i q = 5 ma v adj/en = 5 v
