TDA3617

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 ≤ 1.3 A 1 mA ≤ IREG2 ≤ 600 mA; VP = 14.4 V 1 mA ≤ IREG3 ≤ 300 mA t ≤ 10 minutes for 50 ms; tr ≥ 2.5 ms standby mode 9.5 − − − − 8.55 4.75 3.14 14.4 − − 5 − 9.0 5.0 3.3 PARAMETER CONDITIONS MIN.
