FUNCTIONAL DESCRIPTION

The TDA3663 is a fixed 3.3 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 device remains operational down to very low supply
voltages and below this voltage it switches off.

Atemperatureprotection circuit is included which switches
off the regulator output 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
(worst-case) up to 22 Ω, see Figs 5 and 6. This is very
attractive as the ESR of an electrolytic capacitor increases
strongly at low temperatures (no expensive tantalum
capacitor is required).
