Multiple voltage
regulators with switch
FEATURES General Two VP-state controlled
regulators (
regulator 1 and
regulator 3) and a power switch
Regulator 2 and reset circuit operate during load dump and thermal shutdown Separate control pins for switching
regulator 1,
regulator 3 and 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 power switch are switched off) Hold output circuit for
regulator 1 (only valid when
regulator 3 output voltage >1.3 V) Reset and hold outputs (open-collector outputs) Adjustable reset delay time High ripple rejection Backup capacitor connection to supply
regulator 2 and reset circuit up to 25 V. 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 Thermal protection Load dump protection Foldback current limit protection for
regulator 1,
regulator 2 and
regulator 3 ORDERING INFORMATION TYPE NUMBER TDA3608Q TDA3608TH PACKAGE NAME DBS13P HSOP20 DESCRIPTION
TDA3608Q; TDA3608TH
Delayed foldback current limit protection for power switch (at short-circuit); delay time fixed by reset dela...
