TDA3664
Very low dropout voltage/quiescent current 5 V voltage regulator
7. Functional description
The TDA3664 is a fixed 5 V regulator which can deliver output currents up to 100 mA. The
regulator is available in SO8, TSSOP8 and SO4 packages. The regulator is intended for
portable, mains and telephone applications. To increase the lifetime of batteries,
a specially built-in clamp circuit keeps the quiescent current of this regulator very low, also
in dropout and full load conditions.
The regulator remains operational down to very low supply voltages, below which it
switches off.
A temperature protection is included, which switches the regulator output off at
IC temperatures above 150 °C.
