Functional Description
The TLE 4274 is a low-drop voltage regulator in a
TO220 package. The IC regulates an input voltage up
to 40 V to VQrated = 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 over temperature.
Dimensioning Information on External Components
P-TO263-3-1
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 at values CQ ≥ 22 µF and an ESR of ≤ 3 Ω within the operating
temperature range.
