Description The OPTIREG™ Linear TLE4264 is a 5-V low-drop fixed-voltage regulator in an PG-SOT223-4 package. The IC regulates an input voltage VI in the range 5.5 V < VI < 45 V to VQrated = 5.0 V. The maximum output current is more than 120 mA. This IC is shortcircuit-proof and features temperature protection that disables the circuit at overtemperature. Dimensioning information on external components The input capacitor Ci is necessary for compensating line influences. Using a resistor of approx. 1 Ω in series with Ci, the oscillating of input inductivity and input capacitance can be damped. The output capacitor CQ is necessary for the stability of the regulating circuit. Stability is guaranteed at values CQ ≥ 10 µF and an ESR ≤ 10 Ω within the operating temperature range.

Saturation control, working as a function of load current, prevents any over-saturation of the power element. The IC is protected against overload, overtemperature and reverse polarity.
