tsp 4264 5v/ 150ma fixed - voltage ultra low ldo 3 / 6 version: a09 typical application circuit application information dimensioning information on external components the input capacitor c in i s necessary for compensating line influences. using a resistor of approx. 1 in series with c in , t he oscillating of input inductivity and input capacitance can be clamped. the output capacitor c out is necessary for the stability of the regulating circuit. stability is guaranteed at values c out 10u f and an esr 10 within the operating temperature ran ge. circuit description the control amplifier compares a reference voltage, which is kept highly precise by resistance adjustment, to a voltage that is proportional to the output voltage and drives the base of the series transistor via a buffer. saturation control, working as a function of load current, prevents any over - saturation of the power element. the ic is additionally protected against overload, over temperature and reverse polarity
