Functional Description
The TLE 4274 is a low drop voltage regulator available in
a TO220, TO252 and TO263 package. The IC regulates
an input voltage up to 40
V to V
Qrated
= 5.0 V (V50), 8.5 V
(V85) and 10 V (V10). The maximum output current is
400 mA. The IC is short-circuit proof and incorporates
temperature protection that disables the IC at
overtemperature. A 3.3 V and 2.5 V version is also
available. For information about the low output voltage
types please refer to the data sheet TLE
4274 / 3.3 V;
2.5 V.

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 at values
C
Q
≥ 22 μF and an ESR of ≤ 3 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
