FUNCTIONAL DESCRIPTION
The TDA3666 is a fixed 10 V regulator which can deliver
output currents up to 100 mA. The regulator is available in
SO8 and SO4 packages. The regulator is intended for
portable, mains, telephone and automotive 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 and below this voltage it switches off.

A temperature protection circuit is included which switches
the regulator output off at a junction temperature
above 150 C.
A new output circuit guarantees the stability of the
regulator for a capacitor output circuit with an ESR up
to 22
ESR of an electrolytic capacitor increases strongly at low
temperatures (no expensive tantalum capacitor is
required).
