tle 4265 data sheet version 1.01 3 2000-02-09 circuit description the control amplifier compares a highly precise reference voltage, produced by resistor alignment, to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. a saturation control, a function of the load current, prevents any over-saturating of the power element. if the output voltage drops below 4.5 v, the external reset-delay capacitor is discharged by the reset generator. if the voltage on the capacitor reaches the lower threshold v st , a signal is triggered on the reset output and not canceled again until the upper threshold v dt is exceeded. the ic is protected against overload, overtemperature and reverse polarity. figure 1 block diagram saturation control and protection adjustment reset generator buffer + - control amplifier temperature sensor bandgap reference 1 5 4 2 output reset delay reset output in- put gnd 3 aeb01493
