Preliminary specification
Multiple voltage regulator with switch and ignition buffers
FEATURES General • Extremely low noise behaviour and good stability with very small output capacitors • Two VP-state controlled regulators (regulators 1 and 3) and a power switch • Regulator 2, reset and ignition buffer operate during load dump and thermal shutdown • Separate control pins for switching regulators (regulators 1 and 3) and the power switch • Supply voltage range of −18 to +50 V • Low reverse current of regulator 2 • Low quiescent current (when regulator 1, regul
