FUNCTIONAL DESCRIPTION

The TDA3662 is a fixed 3.0 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

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).
