Multiple voltage regulator TDA3617
FEATURES
General
• Three VP-state controlled regulators
(regulators 1, 2 and 3)
• Very good stability and noise behaviour
• Separate controlpins for switching regulators 1, 2 and 3
• Supply voltage range from −18 to +50 V
• Low quiescent current (when regulators 1, 2 and 3 are
switched off)
• High ripple rejection
• Hold output for indicating regulator 1 and/or 2 and/or 3
out-of-regulation.
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 protection 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.
GENERAL DESCRIPTION
The TDA3617 is a multiple output voltage regulator with
three independent regulators. It contains:
1. Three fixed voltage regulators with foldback current
protection (regulators 1, 2 and 3)
2. A supply pin that can withstand load dump pulses and
negative supply voltages
3. Independent enable inputs for regulators 1, 2 and 3
4. Local temperature protection for regulator 3
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.

Multiple voltage regulator TDA3617
FUNCTIONAL DESCRIPTION
The TDA3617 is a multiple output voltage regulator with
threeindependent switchable regulators. Whenthesupply
voltageis available (VP> 4.5 V),regulators 1, 2 and 3 can
be operated by means ofthree 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).

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 enableinputs 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
theTDA3617 are disabled (switched off),the HOLD output
willbe high ohmic. Because ofthis feature, the hold willnot
influence the hold information when wired OR-ed with
other regulator parts.
