Typical Application
1
The input capacitor, CIN, compensates for line fluctuation. Using a resistor of approximately 1 Ω in series with CIN dampens the oscillation of input inductance and input capacitance. The output capacitor, COUT, stabilizes the regulation circuit. The specification for stability is at COUT ≥ 22 μ F and ESR ≤ 5 Ω , within the operating temperature range. Stability for electrolytic capacitors specifically is at COUT ≥ 68 μF within the operating temperature range. See the application report on low-temperature stability, SLVA501, for further details.
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 through a buffer. Saturation control as a function of the load current prevents any oversaturation of the power element. The device also incorporates a number of internal circuits for protection against: overload , overtemperature , and reverse polarity .
