plastic DIL-bent-SIL power package; 17 leads (lead length 7.7 mm) plastic DIL-bent-SIL (special bent) power package; 17 leads (lead length 12 mm) plastic, heatsink small outline package; 20 leads; low stand-off height 2 • ESD protection on all pins • Thermal protections • Load dump protection TDA3681 • Foldback current limit protection for regulators 1, 2,.

Features

General
• Extremely low noise behaviour and good stability with very small output capacitors
• Second supply pin for regulators 3 and 4 to reduce power dissipation (e.g. via a DC-to-DC converter)
• Three VP-state controlled regulators (regulators 1, 3 and 4) and a power switch
• Regulator 2, reset and ignition buffer operational during load dump and thermal shutdown
• Combined control pin for switching regulators 1 and 3
• Separate control pins for switching regulator 4 and the power switch
• Supply voltage range from −18 to +50 V
• Low quiescent current in standby mode (when regulators 1, 3 a.
