3 / 4 page TS4266G Preliminary 3-3 2004/12 rev. A Typical Application Circuit Application Information Dimensioning Information on External Components The input capacitor Cin is necessary for compensating line influences (100nF ceramic capacitor recommended). Using a resistor of approx. 1Ω in series with Cin, the oscillating of input inductivity and input capacitance can be clamped. In the application circuit shown, an additional electrolytic input capacitor of 470uF is added in order to buffer supply line influences. This capacitor is recommended, if the device is sourced via long supply lines of several meters. The output capacitor Cout is necessary for the stability of the regulating circuit. Stability is guaranteed at values Cout ≥10uF and an ESR ≤ 4Ω within the operating temperature range. Circuit Description The control amplifier compares a reference voltage of 2.5V typical, the regulation loop controls the output to achieve an output voltage of 5V with an accuracy of +/-2% at an input voltage up to 45V. The minimum required input voltage is Vout + Vdrop. The TS4266G can supply up to 150mA. However for protection reasons at high input voltage above 25V, the maximum output current is reduced (SOA protection). The IC is additionally protected against overload, over temperature and reverse polarity |
