Functional Description
The TLE 4287 G is a monolithic integrated 5 V voltage regulator in P-DSO-14-8
package. It supplies an output current
incorporates temperature protection which turns off the device at overtemperature.
The input voltage
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
generated by setting the reset output LOW. The reset delay time can be set by choosing
the external capacitor over a wide range. When the output voltage rises above
voltage reaches the upper switching threshold the reset output pin is set HIGH again.
