TLE 4266

Circuit Description

The device includes a precise reference voltage, which is very accurate due to resistor

adjustment. A control amplifier compares the divided output voltage to this reference

voltage and drives the base of the PNP series transistor through a buffer.

Saturation control as a function of the load current prevents any oversaturation of the

power element. The IC also incorporates a number of protection circuitry for:

• Overload

• Overtemperature

• Reverse polarity
