Preliminary specification
Very low dropout voltage/quiescent current
adjustable voltage regulator
TDA3661
FUNCTIONAL DESCRIPTION
The TDA3661 is an adjustable voltage regulator with an
output voltage that can be fixed by means of an external
resistor divider. The regulator 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, in dropout
and full load conditions.
The device remains operational down to very low supply
voltages (typical 2 V) and below this voltage it switches off.

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
20
. If only a 100 nF capacitor is used, the regulator is
fully stable when I

> 200
μ
A. This is very attractive as
the ESR of an electrolytic capacitor increases strongly at
low temperatures (no expensive tantalum capacitor is
required).
LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 134).
