TDA3617

General
` Three VP-state controlled regulators (regulators 1, 2 and 3)
` Very good stability and noise behaviour
` 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
` 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.

The TDA3617J is a multiple output voltage regulator with three independent regulators. TDA3617 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.
