FUNCTIONAL DESCRIPTION
The TDA3682 is a multiple output voltage regulator with
power switches, intended for use in car radios with or
without a microprocessor.
It contains:
Four switchable regulators and one permanent active
regulator
Two power switches with loss of ground protection
Three enable control inputs EN1, EN2 and EN3.
The quiescent current has a very low level of 120
A
(typical value) with the regulator 2 (BU5V) active.
Because of low voltage operation of the application, low
dropout voltage regulators are used in the TDA3682.
Output selection
Regulator 2 is always active and can not be controlled.
All the other regulators and both power switches can be
controlled by using pins EN1, EN2 and EN3:
Pin EN1 controls regulator 1 (illumination); see Table 1
Pin EN2 selects regulator 3, 4 or 5 (audio, AM or FM);
see Table 2
Pin EN3 selects power switches 1 or 2 (PANT or
PCON); see Table 3.
Pins EN2 and EN3 are three-state level control inputs:
L means: V
EN
1 V
M means: 2 V

3 V
H means: V

Table 3

Protections
All output pins are fully protected against load dump and
short-circuit (foldback current protection); see Fig.3.
At load dump all regulator outputs will go low, except the
output of regulator 2 (BU5V).
The power switches can withstand `loss of ground'. This
means that the ground pin is disconnected and the switch
output is connected to ground.
Backup function
A backup function is present. This is realized by a switch
function which acts like a sort of ideal diode between
pins V
P2
and STCP. The forward voltage of this ideal diode
depends on the current flowing through this diode. This
function makes it possible to supply regulator 2 (BU5V)
when no supply voltage is present on pin V
P2
. A special
application can be made using a backup function by
connecting a capacitor between pin STCP and ground.
When the supply voltage is present on pin V
P2
this
capacitor will be charged to a level of V
P2
-
0.3 V. This
charge can now be used to supply regulator 2 for a short
period of time when V
P2
is switched to 0 V.
The delay time can be calculated using the formula:
Example: V
P2
= 14.4 V, V
REG2
= 5 V, R
L
= 1 k
and
C
backup
= 100
F results in a delay time of 177 ms.
When an overvoltage condition occurs, the voltage on
pin STCP will be limited to approximately 18 V.

2. The dropout voltage of a regulator is the voltage difference between V
P2
and V
o(REG)
.
3. The foldback current protection limits the dissipation power at short-circuit.
4. The dropout voltage of regulator 2 is the voltage difference between V
STCP
and V

and depends on the load
current (see Fig.6).
5. The dropout voltage of regulator 2 is the voltage difference between V

Application information
N
OISE
The outputs of regulators 1 to 5 are designed in such a
way that the noise is very low and the stability is very good.
The noise output voltage depends on output capacitor C
o
.
Table 4 shows the influence of the output capacitor on the
noise figure.
Table 4
Noise figures
Note
1. Measured at a bandwidth from 20 Hz to 20 kHz.
S
TABILITY
The regulators are made stable with the externally
connected output capacitors. The stability can be
guaranteed with almost any output capacitor. When only
an electrolytic capacitor is used, the temperature
behaviour of this output capacitor can cause oscillations at
extreme low temperature. The following two examples
show how an output capacitor value is selected.
Oscillation problems can be avoided by adding a 47 nF
capacitor in parallel with the electrolytic capacitor.
Example 1 (regulator 2)
Regulator 2 (BU5V) is stabilized with an electrolytic output
capacitor of 10
F (ESR = 4
). At T
amb
=
-
30
C the
capacitor value is decreased to 3
F and the ESR is
increased to 28
. As can be seen from Fig.8 the regulator
will be instable at T
amb
=
-
30
C.
Solution: To avoid problems with stability at low
temperatures, the use of tantalum capacitors is
recommended. Use a tantalum capacitor with a value of
10
F or an electrolytic capacitor with a higher value.
Example 2 (regulator 1)
Regulator 1 (illumination) is stabilized with an electrolytic
capacitor of 2.2
F (ESR = 8
). At T
amb
=
-
30
C the
capacitor value is decreased to 0.8
F and the ESR is
increased to 56
. As can be seen from Fig.9 the regulator
will be stable at T
amb
=
-
30
C.
Even when only a small MKT capacitor of 47 nF is used as
the output capacitor, regulator 1 will remain stable over the
temperature range.

SOLDERING
Introduction to soldering through-hole mount
packages
This text gives a brief insight to wave, dip and manual
soldering. 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).
Wave soldering is the preferred method for mounting of
through-hole mount IC packages on a printed-circuit
board.
Soldering by dipping or by solder wave
The maximum permissible temperature of the solder is
260
C; solder at this temperature must not be in contact
with the joints for more than 5 seconds.
The total contact time of successive solder waves must not
exceed 5 seconds.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T
stg(max)
). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
Manual soldering
Apply the soldering iron (24 V or less) to the lead(s) of the
package, either below the seating plane or not more than
2 mm above it. If the temperature of the soldering iron bit
is less than 300
C it may remain in contact for up to
10 seconds. If the bit temperature is between
300 and 400
C, contact may be up to 5 seconds.
Suitability of through-hole mount IC packages for dipping and wave soldering methods
Note
1. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.
