TEA7610 LOW-DROP VOLTAGE REGULATOR s s s s s VO = 10V ± 4 % (IO = 5mA) IO = 5 TO 500mA VI ­ VO = 0.6 V (IO = 500mA) VI (surge) = ± 80V THERMAL AND SHORT-CIRCUIT PROTECTION TO220 (Plastic Package) ORDER CODE : TEA7610SP PIN CONNECTIONS GND 1 = VI 2 = VO 3 = GND DESCRIPTION TEA7610 is a low-drop regulator well suited to supplying stabilized voltage to µPs in harsh industrial environment. Special care was taken to keep : - Lowest possible output capacitor (1µF).

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 to 1 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).
