TDA3618AJR Overview
The TDA3618AJR is a multiple output voltage regulator with a power switch and ignition buffers, intended for use in car radios with or without a microcontroller. Two fixed voltage regulators with foldback current protection (regulators 1 and 3) and one fixed voltage regulator (regulator 2) intended to supply a microcontroller, that also operates during load dump and thermal shutdown A power switch with protection,...
TDA3618AJR Key Features
- Extremely low noise behaviour and good stability with very small output capacitors
- Two VP-state controlled regulators and a power switch
- Regulator 2, reset and ignition buffer operate during load dump and thermal shutdown
- Separate control pins for switching regulator 1, regulator 3 and the power switch
- Supply voltage range from -18 to +50 V
- Low reverse current of regulator 2
- Low quiescent current when regulator 1, regulator 3 and the power switch are switched off
- Hold output for low VP
- Hold output for regulators 1 and 3
- Hold output for foldback mode switch
