FEATURES
GENERAL DESCRIPTION
The TDA3603 is a multiple output voltage regulator with a
power switch, intended for use in car radios with or without
a microcontroller.
General
• One VP state controlled regulator (regulator 2)
• Regulator 2, reset and ignition buffer operate during
It contains one fixed voltage regulator with a foldback
current protection (regulator 1) and one fixed voltage
regulator (regulator 2), intended to supply a
microcontroller, that also operates during load dump and
thermal shutdown.
load dump and thermal shutdown
• One control pin for switching regulator 1 and the power
switch
• Supply voltage range of −18 to +50 V (operating
from 9.75 V)
There is a power switch with protections, operated by the
enable input.
• Low reverse current of regulator 2
• Low quiescent current (when regulator 1, power switch
and ignition input are switched off, standby)
The reset and ignition outputs can be used to interface by
the microcontroller. The reset signal can be used to call up
the microcontroller and the ignition output indicates
ignition voltage available.
• Ignition input/output
• Reset output
• High ripple rejection
• Power switch.
The supply pin can withstand load dump pulses and
negative supply voltages.
Regulator 2 will be switched on at a supply voltage >6.5 V
and off at a voltage of regulator 2 <1.9 V.
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 shortened)
• ESD protected on all pins
• Thermal protection
• Load dump protection
• Foldback current limit protection for regulators 1 and 2
• Delayed second current limit protection for the power
switch
• The regulator outputs and the power switch are DC
short-circuited safe to ground and VP.

Product specification
Multiple voltage regulator with switch
TDA3603
All output pins are fully protected. The regulators are
protected against load dump (regulator 1 will switch off at
supply voltages higher than 25 V) and short-circuit
(foldback current protection).
The switch contains a current protection which is delayed
for ≥10 ms (in short-circuit condition). During this time the
current is limited to 1.4 A (VP ≤ 18 V).
FUNCTIONAL DESCRIPTION
The TDA3603 is a multiple output voltage regulator with a
power switch, intended for use in car radios with or without
a microcontroller. Because of low-voltage operation of the
car radio, low-voltage drop regulators are used.
Regulator 2 will switch on when the supply voltage
exceeds 6.5 V for the first time and will switch off again
when the output voltage of regulator 2 is below 1.9 V (this
is below an engine start). When regulator 2 is switched on
and the output voltage of this regulator is within its voltage
range, the reset output will be enabled (reset will go HIGH
via a pull-up resistor) to generate a reset to the
microcontroller. The reset cycles can be extended by an
external capacitor at the reset output (pin 3). The start-up
feature is built-in to ensure a smooth start-up of the
microcontroller at first connection, without uncontrolled
switching of regulator 2 during the start-up sequence.
At supply voltages over 16.9 V the switch is clamped at
15.0 V (to avoid externally connected circuitry being
damaged by an overvoltage) and the switch will switch off
at load dump.
Interfacing with the microcontroller can be accomplished
by an ignition Schmitt trigger and ignition output buffer,
(simple full/semi on/off logic applications).
The total timing of a semi on/off logic set is shown Fig.4.
When both regulator 2 and the supply voltage (VP > 4.5 V)
are available, regulator 1 and the switch can be operated
by an enable input (pin 4).

Noise information
Table 1 Noise figures
The noise at the output of the regulators depends on the
bandwidth of the regulators, which can be adjusted by the
output capacitors. Table 1 shows the noise figures.

Although stability is guaranteed when CL is higher than
10 µF (over temperature range) with tan (φ) = 1 in the
frequency range 1 to 10 kHz, however, for low noise, a
47 µF load capacitor is required. When electrolytic
capacitors are used, the capacitor value will decrease and
the ESR will increase much at low temperatures. To avoid
oscillation a normal capacitor of 220 nF can be placed in
parallel with this electrolytic capacitor.

Note
1. Bandwidth of 100 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 into a current noise by
the output capacitors). When a high frequency capacitor of
220 nF with an electrolytic capacitor of 100 µF in parallel is
placed directly over pins 1 and 6 (supply and ground) the
noise is minimized.

There is an application solution to protect against ‘loss of
ground’ (see Fig.8).
SHORT CIRCUIT BEHAVIOUR OF POWER SWITCH
The short circuit behaviour of the switch with large
inductive loads (switch output goes out of the radio) can be
improved by replacing C2 (see Fig.7) by a larger
electrolytic capacitor of 10 µF/16 V. When the temperature
protection of the switch becomes active, due to a short
circuit of the switch, the behaviour will be improved.
It is advisable to limit the dissipation at short circuit
condition by monitoring the output of the power switch.
The microprocessor can switch of the power switch when
the switch was enabled and the switch output remains low
due to a short circuit condition.
When the switch is clamped an minimum output capacitor
of 10 µF is needed.
The power switch is not protected against ‘loss of ground’
condition (= short of the switch to ground with floating
ground pin of the TDA3603 itself). A ‘loss of ground’
situation can in practice only occur when the switch output
goes outside the car-radio box.

5 seconds.
SOLDERING
Introduction
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.
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
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).
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.
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

Limiting values
Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or
more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation
of the device at these or at any other conditions above those given in the Characteristics sections of the specification
is not implied. Exposure to limiting values for extended periods may affect device reliability.
