Functional Description
TLE 4266 G is a 5-V low-drop voltage regulator in a P-SOT223-4-2 SMD package. The
IC regulates an input voltage V_i in the range of 5.5 V < V_i < 45 V to V_Qrated = 5 V / 10 V.
The maximum output current is more than 120 mA. The IC can be switched off via the
inhibit input, which causes the current consumption to drop below 10 µA. The IC is
shortcircuit-proof and incorporates temperature protection that disables the IC an
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 clamped. 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.
