FEATURES
• Thermal protection
General
• Load dump protection
• Three VP-state controlled regulators
(regulators 1, 2 and 3)
• Foldback current limit protection for
regulators 1, 2 and 3
• DC short-circuit safe to ground and VP for all regulator
outputs.
• Very good stability and noise behaviour
• Separate control pins for switching regulators 1, 2 and 3
• Supply voltage range from −18 to +50 V
GENERAL DESCRIPTION
• Low quiescent current (when regulators 1, 2 and 3 are
switched off)
The TDA3617 is a multiple output voltage regulator with
three independent regulators. It contains:
• High ripple rejection
1. Three fixed voltage regulators with foldback current
protection (regulators 1, 2 and 3)
• Hold output for indicating regulator 1 and/or 2 and/or 3
out-of-regulation.
2. A supply pin that can withstand load dump pulses and
negative supply voltages
Protections
• Reverse polarity safe (down to −18 V without high
reverse current)
3. Independent enable inputs for regulators 1, 2 and 3
• Able to withstand voltages up to 18 V at the outputs
(supply line may be short circuited)
5. A hold output that can be used to interface with a
microprocessor. The hold indicates that the selected
output voltages are available and within their ranges.
4. Local temperature protection for regulator 3
• ESD protection on all pins

Product specification
Multiple voltage regulator
TDA3617
The TDA3617 has a hold circuit which indicates when one
of the regulators is out-of-regulation. The hold function is
disabled when all the enable inputs are LOW (TDA3617 in
standby mode). The HOLD output (open-collector output)
can be wired OR-ed with other hold outputs of other
regulator parts (e.g. TDA3618). When all the regulators of
the TDA3617 are disabled (switched off), the HOLD output
will be high ohmic. Because of this feature, the hold will not
influence the hold information when wired OR-ed with
other regulator parts.
FUNCTIONAL DESCRIPTION
The TDA3617 is a multiple output voltage regulator with
three independent switchable regulators. When the supply
voltage is available (VP > 4.5 V), regulators 1, 2 and 3 can
be operated by means of three independent enable inputs.
Schmitt trigger functions are included to switch the
regulators off at low battery voltage (VP < 4 V).
A hysteresis is included to avoid random switching.
All output pins are fully protected. The regulators are
protected against load dump (the regulators switch off at
VP > 20 V) and short circuit (foldback current protection).

2. The quiescent current is measured in the standby mode. Therefore, the enable inputs of regulators 1, 2 and 3 are
LOW (Ven < 1 V).
3. The drop-out voltage of regulators 1 and 2 is measured between VP and VREG1 or VREG2 respectively.
4. At current limit, IREGmn is held constant (see Fig.5 for the behaviour of IREGmn).
5. The foldback current protection limits the dissipated power at short circuit (see Fig.5).
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.

The regulators are stabilized with the externally connected

When an electrolytic capacitor is used, its temperature
behaviour can cause oscillations at Tamb < −20 °C. In this
case, use a tantalum capacitor.

Note
1. Measured at a bandwidth of 200 kHz.
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 to a current noise by
means of the output capacitors). The noise is minimum
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).

At Tamb = −30 °C the capacitor value is decreased to

Use a 47 nF HF capacitor in parallel with the output

The total contact time of successive solder waves must not
exceed 5 seconds.
SOLDERING
Introduction to soldering through-hole mount
packages
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.
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.
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.
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.
