Application Circuit
Input, Output
The input capacitor
C
I
is necessary for compensating line influences. Using a resistor of
approx. 1
in series with
C
I
, the LC circuit of input inductivity and input capacitance can
be damped. To stabilize the regulation circuits of the stand-by and main regulator, output
capacitors
C
Q1
and
C
Q2
are necessary. Stability is guaranteed at values
C
Q1
(ESR 2 ) and
C
Q2
10 F (ESR
3
) within the operating temperature range.
Enable
Using the enable feature the output 2 (5 V output) can be switched ON or OFF. The
enable input can be connected directly to terminal 30 (battery line) or 15 (ignition line). It
is also possible to control the output 2 via the microcontroller.
