Using a resistor of approx. 1 Ω in series with CI, the oscillating of input inductivity and input capacitance can be damped. The output capacitor CQ is necessary for the stability of the regulation circuit. Stability is guaranteed at values CQ ≥ 22 µF and an ESR of ≤ 3 Ω within the operating temperature range. Circuit Description The control amplifier compares a reference voltage to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. Saturation control as a function of the load current prevents any oversaturation of the power element. The IC also includes a number of internal circuits for protection against: • • • Overload Overtemperature Reverse polarity Data Sheet 2 Rev. 1.6, 2007-01-23 TLE 4274 PG-TO220-3-1 PG-TO252-3-11 PG-TO263-3-1 GND Ι Q AEP02512 Ι GND Q AEP02281 Ι GND Q AEP01957 Figure 1 Table 1 Pin No. 1 2 3 I Pin Configuration (top view) Pin Definitions and Functions Symbol GND Q Function Input; block to ground directly at the IC with a ceramic capacitor.
