FEATURES
GENERAL DESCRIPTION
• Three VP-state controlled regulators (regulator 1,
regulator 2 and regulator 3)
The TDA3607 is a multiple output voltage regulator with
three independent regulators. It contains:
• Separate control pins for switching regulators 1, 2 and 3 1. Three fixed voltage regulators with foldback current
protection (regulators 1, 2 and 3)
• Supply voltage range from −18 to +50 V
2. A supply pin which can withstand load dump pulses
• Low quiescent current (when regulators 1, 2 and 3 are
switched off)
and negative supply voltages
3. Independant enable inputs for regulators 1, 2 and 3
• High ripple rejection.
4. Local temperature protection for regulator 3.
PROTECTIONS
• Reverse polarity safe (down to −18 V without high
reverse current)
• Able to withstand voltages up to 18 V at the outputs
(supply line may be short-circuited)
• ESD protected on all pins
• Thermal protection
• Load dump protection
• Foldback current limit protection for
regulators 1, 2 and 3
• DC short-circuit safe to ground and VP for all regulator
outputs.

Preliminary specification
Multiple voltage regulator with switch
TDA3607
All output pins are fully protected. The regulators are
protected against load dump (regulators will switch-off at
supply voltages higher than 20 V) and short-circuit
(foldback current protection).
FUNCTIONAL DESCRIPTION
The TDA3607 is a multiple output voltage regulator with
three independent switchable regulators. When the supply
voltage (VP > 4.5 V) is available, regulators 1, 2 and 3 can
be operated by means of 3 independent enable inputs.
The total timing of a semi on/off logic set is shown in Fig.3.
Schmitt-trigger functions are included to switch-off the
regulators at low battery voltage (VP < 4 V). A hysteresis is
included to avoid random switching.

Notes
1. Minimum operating voltage, only if VP has exceeded 4.5 V.
2. The quiescent current is measured in the standby mode. So, the enable inputs of regulator 1, 2 and 3 are LOW
(Ven < 1 V).
3. The drop-out voltage of regulators 1, 2 and 3 is measured between VP and VREGn
4. At current limit, IREGmn is held constant (see Fig.4 for behaviour of IREGmn).
.
5. The foldback current protection limits the dissipated power at short-circuit (see Fig.4).
6. Perform the load regulation test with sine wave load of 10 kHz on the regulator output under test. Measure the RMS
ripple voltage on each of the remaining regulator outputs, using a 80 kHz low-pass filter.

When a high frequency capacitor of 220 nF in parallel with
an electrolytic capacitor of 100 µF is connected directly to
pins 3 and 8 (supply and ground) the noise is minimal.

Note
1. Measured at a bandwidth of 200 kHz.
The following two examples explain how an output
capacitor value is selected.
The noise on the supply line depends on the value of the
supply capacitor and is caused by a current noise (output
noise of the regulators is translated into a current noise by
means of the output capacitors).

Example 1
Solution
Regulator 1 is made stable with an electrolytic output
capacitor of 68 µF (ESR = 0.5 Ω), at −30 °C the capacitor
value is decreased to 22 µF and the ESR is increased to
3.5 Ω. The regulator will remain stable at −30 °C.
Use a tantalum capacitor of 10 µF or a large electrolytic
capacitor. The use tantalum capacitors is recommended to
avoid problems with stability at cold temperatures.
Example 2
Regulator 2 is made stable with a 10 µF electrolytic
capacitor (ESR = 3.3 Ω), at −30 °C the capacitor value is
decreased to 3 µF and the ESR is increased to 23.1 Ω.
The regulator will be unstable at −30 °C (see Fig.7).

Preliminary specification
Multiple voltage regulator with switch
TDA3607
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 (Tstg 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.
SOLDERING
Introduction
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.
Repairing soldered joints
Apply a low voltage soldering iron (less than 24 V) to the
lead(s) of the package, 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.
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our “IC Package Databook” (order code 9398 652 90011).
Soldering by dipping or by wave
The maximum permissible temperature of the solder is
260 °C; solder at this temperature must not be in contact
with the joint for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
