TLE4675 voltage regulator data sheet 10 rev. 1.0, 2008-09-30 5 voltage regulator 5.1 description voltage regulator the output voltage v q is controlled by comparing a portion of it to an internal reference and driving a pnp pass transistor accordingly. saturation cont rol as a function of the load current prevents any oversa turation of the pass element. the control loop stability depends on the ou tput capacitor c q , the load current, the chip temperature and the poles/zeros introduced by the integrated circuit. to ensure stable operation, the output capacitor?s capacitance and its equivalent series resistor esr requirements gi ven in the table ?operating range? have to be maintained. for details see also the 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 not needed for the control loop stability, but recommended to bu ffer line influences. 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 input voltages above v i =22v. the thermal shutdown circuit prevents the ic from i mmediate destruction under fault conditions (e.g. output continuously short-circuited) by switching off the power stage. after the chip has cooled down, the regulator restarts. this leads to an oscillatory behavior of the output volt age until the fault is re moved. however, junction temperatures above 150 c are outside the maximum ratings a nd therefore reduce the ic lifetime. the TLE4675 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. figure 4 block diagram volt age regulator circuit figure 5 output voltage vs. input voltage bandgap reference gnd q i b lockdiagram _v oltageregulator .vsd saturation control current limitation temperature shutdown c q load supply c i regulated output voltage i q i i v q + v i + 9 w 'ldjudpb2xwsxw,qsxw9rowdjhvyj 9 4qrp 9 , 9 gu 9 4 g 9 4 g w , ordg & 4 g 9 4 g w , 4pd[ , ordg & 4 9 ,h[wplq
