(1) It is understood that for VI(3.3V)< 3 V, voltages within the absolute maximum ratings applied to pin 5 V or pin 12 V will not damage the IC.
ELECTRICAL CHARACTERISTICS
TJ = 25°C, VI(5V) = 5 V, VI(3.3V) = 3.3 V, VI(12V) = 12 V, all outputs unloaded (unless otherwise noted)

(1) Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account separately.
(2) TPS2204A and TPS2206A: two switches on. TPS2210A: one switch on.
(3) Specified by design; not tested in production.
(4) From application of short to 110% of final current limit.
