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.

P-TO252-3-1

Dimensioning Information on External Components

The input capacitor C_Iis 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_Qis 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.

Circuit Description

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 via a buffer. Saturation control

as a function of the load current prevents any oversaturation of the power element. The

IC also includes a number of internal circuits for protection against:

• Overload

• Overtemperature

• Reverse polarity
