INTEGRATED CIRCUITS DATA SHEET TDA3617 Multiple voltage regulator Preliminary specification File under Integrated Circuits, IC01 1999 Jul 14 Philips Semiconductors Preliminary specification Multiple voltage regulator FEATURES 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 QUICK REFERENCE DATA SYMBOL Supply VP supply voltage operating jump start load dump protection Iq(tot) Tj VREG1 VREG2 VREG3 total quiescent current junction temperature 1 mA ≤ IREG1 ≤ 1.

GENERAL DESCRIPTION The TDA3617J 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.
