Using a resistor of approx. 1Ω in series with CIN, the oscillating of input inductivity and input capacitance can be clamped. The output capacitor COUT is necessary for the stability of the regulating circuit. Stability is guaranteed at values COUT ≥10uF and an ESR ≤ 10Ω within the operating temperature range. 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 3/6 Version: A09 TSP4264 5V/150mA Fixed-Voltage Ultra Low LDO Electrical Characteristics Curve Figure 1.
