The device regulates an input voltage up to 45 V to VOUT = 5 V (typical). The device can drive loads up to 450 mA and is short-circuit proof. At overtemperature, the incorporated temperature protection turns off the TLE4275-Q1. The device generates a reset signal for an output voltage, VOUT,rt, of 4.65 V (typical). By the use of an external delay capacitor, one can program the reset delay time. 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 μF and ESR ≤ 5 Ω, within the operating temperature range. Stability for electrolytic capacitors specif...
