In the fixed voltage TLE 4284 devices the output voltage is divided internally and
compared to an internal reference of 1.25 V typical. The regulation loop controls the
output voltage to achieve the output voltage of 5 V, 3.3 V or 2.5 V. The variable device
compares the voltage difference between the adjust pin ADJ and the output pin Q to the
internal reference of 1.25 V; the output voltage is adjusted by an external voltage divider
between Q, ADJ and GND (see equation in
Figure 7
).
Output
The output current limitation is reduced as a function of the input voltage for high input
voltages above 25 V.
The TLE 4284 requires no output capacitor for stability, however we recommend to use
a ceramic capacitor to filter any noise and improve the transient response.
At the input of the regulator a capacitor is necessary for compensation of line influences.
A resistor of approx. 1
in series with
C
I
can damp the LC of the input inductivity and
the input capacitor. A serial diode should be used to eliminate negative voltages from the
input.
For the variable voltage type an additional decoupling a capacitor
C
ADJ
at the adjust pin
can improve the ripple rejection ratios.
