P-SOT223-4
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 VQrated = 3.3 V/2.5 V. The maximum output current is 400 mA. The IC is shortcircuit 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 CI is necessary for compensating line influences. Using a resistor of approx. 1 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 regulation circuit. Stability is guaranteed for capacities CQ 10 F with an ESR of 2.5 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
