Multiple voltage regulator with switch TDA3607
FEATURES
• Three VP-state controlled regulators (regulator 1,
regulator 2 and regulator 3)
• Separate control pins 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.
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 V
for all regulator

outputs.
GENERAL DESCRIPTION
The TDA3607 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 which can withstand load dump pulses
and negative supply voltages
3. Independant enable inputs for regulators 1, 2 and 3
4. Local temperature protection for regulator 3.

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.
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.

load dump
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).
The total timing of a semi on/off logic set is shown in Fig.3.
