The TLE 4287 G is a monolithic integrated 5-V voltage regulator in P-DSO-14-4 package. It supplies an output current IQ > 250 mA. The IC is short circuit proof and incorporates temperature protection that disables it at overtemperature.
The input voltage VI is regulated in the range of 7.5 V < VI < 40 V to VQrated = 5 V. Therefore a reference voltage, which is kept highly accurate by resistance adjustment, is compared via a control amplifier to a voltage that is proportional to the output voltage. The control amplifier drives the base of the series transistor by a buffer.
A comparator in the reset-generator block compares a reference voltage that is independent of the input voltage to the scaled-down output voltage. In the case of an output voltage VQ < 4.5 V the reset delay capacitor is discharged and a reset signal is generated by setting the reset output LOW. The reset delay time can be set by an external capacitor within a wide range. When the output voltage rises above VQ 4.5 V the reset delay capacitor is charged again. As soon as the delay capacitor voltage reaches the upper switching threshold the reset output pin is set HIGH again.
