Functional Description
The TLE 4274 / 3.3V;2.5V is a voltage regulator available
in a SOT223 and TO252 package. The IC regulates an
input voltage up to 40 V to V_Qrated = 3.3 V/2.5 V. The
maximum output current is 400 mA. The IC is short-
circuit proof and has a shutdown circuit protecting it
against overtemperature. The TLE 4274 is also available
as 5 V, 8.5 V and 10 V version. Please refer to the data
sheet TLE 4274.

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 regulation circuit.
Stability is guaranteed for capacities C_Q ≥ 10 µF with an ESR of ≤ 2.5 Ω within the
operating temperature range.
