TLE 4278 G
Application Information
Input, Output
The input capacitors
C
I1
and C
I2
are necessary for compensating line influences. Using
a resistor of approx. 1 Ω in series with
C
I1
, the LC circuit of input inductance and input
capacitance can be damped. To stabilize the regulation circuit the output capacitor
C
Q
is
necessary. Stability is guaranteed at values
C
Q
≥ 10 µF with an ESR ≤ 5 Ω within the
operating temperature range.
