FUNCTIONAL DESCRIPTION
A temperature protection is included, which switches the
regulator output off at IC temperatures above 150 °C.
The TDA3664 is a fixed 5 V regulator which can deliver
output currents up to 100 mA. The regulator is available in
SO8, TSSOP8 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.
A new output structure guarantees the stability of the
regulator with an ESR up to 38 Ω. This is very attractive as
the ESR of an electrolytic capacitor increases strongly at
low temperatures (no expensive tantalum capacitor
required).
The regulator remains operational down to very low supply
voltages, below which it switches off.

Stability
The regulator is stabilized with an external capacitor on the
output. The value of this capacitor can be selected using
the diagrams shown in Figs 5 and 6. The four examples on
the next page show the effects of the stabilization circuit
using different values for the output capacitor.

EXAMPLE 1
Application circuit with backup function
The regulator is stabilized with an electrolytic output
capacitor of 68 µF (ESR = 0.5 Ω). At −40 °C, the capacitor
value is decreased to 22 µF and the ESR is increased to
3.5 Ω. The regulator will remain stable at a temperature of
−40 °C.
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).
This function can be easily built with the TDA3664 by using
a large output capacitor. When the supply voltage is 0 V
(or −1 V), only a small current will flow into pin REG from
this large output capacitor (a few µA).
EXAMPLE 2
The regulator is stabilized with an electrolytic output
capacitor of 10 µF (ESR = 3.3 Ω). At −40 °C, the capacitor
value is decreased to 3 µF and the ESR is increased to
20 Ω. The regulator will remain stable at a temperature of
−40 °C.
The application circuit is given in Fig.7.
EXAMPLE 3
The regulator is stabilized with a 100 nF MKT capacitor on
the output. Full stability is guaranteed when the output
current is over 200 µA.

Because the thermal influence on this capacitor value is

EXAMPLE 4
The regulator is stabilized with a 100 nF capacitor in
parallel with a electrolytic capacitor of 10 µF on the output.
(1) C1 is optional (to minimize supply noise only).
(2) C2 ≤ 4700 µF.
(3) VREG = 5 V.
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.
Application circuits

When Tamb = 21 °C, the maximum output current equals
140 mA at VP =14 V.
The total thermal resistance of the TDA3664 (SOT223-1
package) can be decreased to lower values when pin 4
and body of the package are soldered to the printed-circuit
board.

SOLDERING
If wave soldering is used the following conditions must be
observed for optimal results:
Introduction to soldering surface mount packages
• Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
This text gives a very brief insight to a complex technology.
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).
• 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;
There is no soldering method that is ideal for all surface
mount IC packages. Wave soldering is not always suitable
for surface mount ICs, or for printed-circuit boards with
high population densities. In these situations reflow
soldering is often used.
– smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
Reflow soldering
The footprint must incorporate solder thieves at the
downstream end.
Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.
• For packages with leads on four sides, the footprint 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.
Several methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 100 and 200 seconds depending on heating
method.
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 reflow peak temperatures range from
215 to 250 °C. The top-surface temperature of the
packages should preferable be kept below 230 °C.
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.
Wave soldering
Manual soldering
Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.
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.
To overcome these problems the double-wave soldering
method was specifically developed.
When using a dedicated tool, all other leads can be
soldered in one operation within 2 to 5 seconds between
270 and 320 °C.

Notes
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the “Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”.
2. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).
3. If wave soldering is considered, then the package must be placed at a 45° angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.
4. Wave soldering is only suitable for LQFP, TQFP and QFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
5. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
