Features
Functional Description
The TLE 4287 G is a monolithic integrated 5 V voltage regulator in PG-DSO-14
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
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.
