Functional Description
TLE 4264 is a 5-V low-drop fixed-voltage regulator in an PG-SOT223-4 package. The IC
regulates an input voltage V_I in the range 5.5 V < V_I < 45 V to V_Qrated = 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 C_i is necessary for compensating line influences. Using a resistor of
approx. 1 Ω in series with C_i, the oscillating of input inductivity and input capacitance can
be damped. The output capacitor C_Q is necessary for the stability of the regulating circuit.
Stability is guaranteed at values C_Q ≥ 10 µF and an ESR ≤ 10 Ω within the operating
temperature range.
