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.

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 VP for all regulator outputs.
