Application Information

In the TLE 4296 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 G output requires an output capacitor CQ of at least 2.2 µF with an

ESR of max. 10 Ω and min. 3 Ω. It is recommended to use tantalum (e.g. the EPCOS

3.3 µF / 16V B45196P3335M209 or 4.7 µF / 10 V B45196-P2475M109) or a multi layer

ceramic capacitor with a series resistor in order to cover these limits 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 CI, can damp any oscillation occurring due the input inductivity and the input

capacitor.
