Application Information
In the TLE 4296-2 G the output voltage is divided and compared to an internal reference
of 2.5 V typical. The regulation loop controls the output to achieve a stabilized output
voltage.
Figure 3 shows a typical application circuit. In order to maintain the stability of the control
loop the TLE 4296-2 G output requires an output capacitor C_Q of at least 3.3 µF with a
maximum permissible ESR of 2 Ω. It is recommended to use a multi layer ceramic
capacitor for C_Q, e.g. the TDK C3216X7R1C475M with a nominal capacitance of 4.7 µF.
Aluminum electrolytic as well as tantalum capacitors do not cover the required ESR
range over the full operating temperature range of -40 °C to 150 °C.
At the input of the regulator an input capacitor is necessary for compensating line
influences (100 nF ceramic capacitor recommended). A resistor of approx. 1 Ω in series
with C_I, can damp any oscillation occurring due the input inductivity and the input
capacitor. If the regulator is sourced via long input lines of several meters it is
recommended to place an additional electrolytic capacitor ≥ 47 µF at the input.
