DESCRIPTION
TEA7610 is a low-drop regulator well suited to
supplying stabilized voltage to µPs in harsh indus-
trial environment.
Special care was taken to keep :
- Lowest possible output capacitor (1µF).

NOTE : Applications Hints
The output capacitor has a directinfluence on output voltage stability. A 10 µF capacitor will provide satisfactory results. There is no upper limit
on this capacitor value.
If necessary, this value can be reduced down to1 µF ; however, in such case, it should be checked that output capacitor keeps sufficiently high
capacitance and low equivalent series resistance in the whole temperature range.
Such low capacitor value is not recommended either, if output current is to switch abruptly from very high to very low values (for instance, 400
mA to < 1 mA).
