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).

3.3 V voltage regulator

EXAMPLE 1
The regulator is stabilized with an electrolytic capacitor of

68 µF (ESR = 0.5 Ω). At T
value is decreased to 22 µF and the ESR is increased
to 3.5 Ω. The regulator will remain stable at a temperature
of T

amb

= −40 °C.

EXAMPLE 2
The regulator is stabilized with an electrolytic capacitor of

10 µF (ESR = 3.3 Ω). At T
value is decreased to 3 µF and the ESR is increased to
20 Ω. The regulator will remain stable at a temperature of
T

= −40 °C.

amb

EXAMPLE 3
The regulator is stabilized with a 100 nF MKT capacitor

connected to the output. When the output current is over
200 µA full stability is guaranteed. Because the thermal
influence on the capacitor value is almost zero, the
regulator will remain stable at a temperature of
T

= −40 °C.

amb

EXAMPLE 4
The regulator is stabilized with a 100 nF capacitor in

parallelwith an electrolytic capacitor of 10 µFconnectedto
the output.

The regulator is now stable under all conditions and
independent of:

• The ESR of the electrolytic capacitor

• The value of the electrolytic capacitor

• The output current.

TDA3663

The total thermal resistance of the TDA3663 can be
decreased from 120 K/W to 50 K/W for the SO8 version.
For the SO4 version it can be decreased from
100 to 40 K/WwhenGND pins 2 and 4 of the package are
soldered to the printed-circuit board.

APPLICATION CIRCUIT WITH BACKUP FUNCTION
Sometimes a backup function is needed to supply, for

example, a microcontroller for a short period of time when
the supply voltage spikes to 0 V (or even −1 V).

Thisfunction can easily be built with the TDA3663byusing
an output capacitor with a large value. When the supply
voltage is 0 V (or −1 V), only a small current will flow into
pin REG from this output capacitor (a few µA).

The application circuit is given in Fig.7.

SOLDERING
Introduction to soldering surface mount packages

Thistext gives a very brief insight to acomplextechnology.
A more in-depth account of soldering ICs can be found in
our

“Data Handbook IC26; Integrated Circuit Packages”

(document order number 9398 652 90011).
There is no soldering method that is ideal for all surface

mount IC packages. Wave soldering can still be used for
certainsurface mount ICs, but it isnotsuitable for fine pitch
SMDs. In these situations reflow soldering is
recommended.

Reflow soldering

Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
totheprinted-circuitboardby screen printing, stencilling or
pressure-syringe dispensing before package placement.

Several methods exist for reflowing; for example,
convection or convection/infrared heating in a conveyor
type oven. Throughput times (preheating, soldering and
cooling) vary between 100 and 200 seconds depending
on heating method.

Typical reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 220 °C for
thick/large packages, and below 235 °C for small/thin
packages.

Wave soldering

Conventional single wave soldering is not recommended
forsurface mount devices (SMDs) or printed-circuitboards
with a high component density, as solder bridging and
non-wetting can present major problems.

To overcome these problems the double-wave soldering
method was specifically developed.

TDA3663

If wave soldering is used the following conditions must be
observed for optimal results:

• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.

• For packages with leads on two sides and a pitch (e):
– larger than or equal to 1.27 mm, the footprint

longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;

– smaller than 1.27 mm, the footprint longitudinal axis

must be parallel to the transport direction of the
printed-circuit board.

The footprint must incorporate solder thieves at the
downstream end.

• Forpackages with leads on four sides,thefootprint must
be placed at a 45° angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.

During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.

Typical dwell time is 4 seconds at 250 °C.
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

Manual soldering

Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron applied to the flat part of the lead.
Contact time must be limited to 10 seconds at up to
300 °C.

When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.
