The TLE4275 is a monolithic integrated low-dropout voltage regulator offered in a 5-pin TO package. The device regulates an input voltage up to 45 V to V OUT = 5 V (typ). The device can drive loads up to 450 mA and is short-circuit proof. At overtemperature, the incorporated temperature protection turns off the TLE4275. The device generates a reset signal for an output voltage, V OUT,rt , of 4.65 V (typ). By the use of an external delay capacitor, one can program the reset delay time. The input capacitor, C IN , compensates for line fluctuation. Using a resistor of approximately 1 Ω in series with C IN dampens the oscillation of input inductance and input capacitance. The output capacitor, C OUT , stabilizes the regulation circuit. The specification for stability is at C OUT ≥ 22 µF and ESR ≤ 5 Ω, within the operating temperature range. Stability for electrolytic capacitors specifically is at C OUT ≥ 68 µF within the operating temperature range. See the application report on low-temperature stability, SLVA501, for further details. 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. The device also incorporates a number of internal circuits for protection against: Overload , Overtemperature , and Reverse Polarity .
