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
