data sheet 4 rev. 2.8, 2008-05-19 tle 4262 circuit description the control amplifier compares a reference voltage, which is ke pt highly accurate by resistance adjustment, to a voltage that is proportional to the output voltage and drives the base of the series transist or via a buffer. satu ration control as a function of the load current prevents any over-saturation of the pow er element. if the ex ternally scaled down output voltage at the reset th reshold input drops below 1.35 v, the external reset delay capacitor is discharged by th e reset generator. if the voltag e on the capacitor reaches the lower threshold v drl , a reset signal is is sued on the reset out put and not cancelled again until the upper threshold v du is exceeded. if the reset threshold input is connected to gnd, reset is triggered at an output voltage of 4.5 v. the ic can be switched at the ttl-compatible, low-active inhibi t input. it also incl udes a number of inte rnal circuits for protection against: overload overtemperature reverse polarity figure 2 block diagram aeb01081 control amplifier buffer reference bandgap adjustment protection circuit control and saturation temperature sensor reset generator 6 i q d ro radj 3-5, 10-12 14 inh gnd 1 7 9 13
