Voltage Regulator
TLE 4274 / 3.3V;2.5V
Features
• Output voltage: 3.3 V/2.5 V ± 4%
• Current capability 400 mA
• Very low current consumption
• Short-circuit proof
• Reverse polarity proof
• Suitable for use in automotive electronics
• Green Product (RoHS compliant)
• AEC Qualified
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 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 CI is necessary for compensating line influences. Using a resistor of
approx. 1 Ω 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 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
