data sheet 3 rev. 1.0, 2008-04-21 TLE4263-2ES overview dimensioning information on external components the input capacitor c i is recommended for compensation of line influences. the output capacitor c q is necessary for the stability of the control loop . stability is guara nteed at values 22 f and an esr of 3 ? within the operating temperature range. for small tolerances of the reset delay the capacitance?s spread of the delay capacitor c d and its temperature coefficient should be taken into consideration. circuit description the control amplifier compares a reference voltage to a volt age that is proportional to the output voltage and drives the base of the series transistor via a buffer. saturation control as a function of the load current prevents any oversaturation of the power element. the component also has a number of internal circuits for protection against: ? overload ? overtemperature ? reverse polarity in case the externally scaled down output voltage at the reset adjust input falls below 1.35 v, the external reset delay capacitor c d is discharged by the reset generator. when the voltage of the capacitor reaches the lower threshold v drl , a reset signal occurs at the reset output and is held until the upper threshold v du is exceeded. if the reset threshold input is connecte d to gnd, reset is triggered at an output voltage of typically 4.65 v.
