The TL720M05QKVURQ1 is a monolithic integrated single output low-dropout (LDO) Linear Regulator. The device regulate an input voltage up to 45V to VOUT of 5V with 2% tolerance. The devices can drive loads up to 450mA and are short-circuit proof. At overtemperature, the incorporated temperature protection turns off the device. The input capacitor (CIN) compensates for line fluctuation. Using a resistor of approximately 1R in series with CIN dampens the oscillation of input inductivity and input capacitance. The output capacitor (COUT) stabilizes the regulation circuit. Output is stable at COUT >=22µF and ESR <=5R, within the operating temperature range. 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.
