Preliminary specification
Very low dropout voltage/quiescent current
5 V regulator with overvoltage switch off
TDA3668AT
FUNCTIONAL DESCRIPTION
The TDA3668AT is a fixed 5 V regulator which can deliver
output currents up to 100 mA. The regulator is available in
an SO8 package. 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 at lower voltages it switches off.
A temperature protection 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 up to
38
. This is very attractive as the ESR of an electrolytic
capacitor increases strongly at low temperatures
(no expensive tantalum capacitor is required).
A load dump circuit (see Fig.3) and an overvoltage
protection circuit is built-in which will switch off the IC
above 28 V (typical value).
