The TPS211xA can switch a voltage as low as 1.5 V as long as there is a minimum of 2.8 V at one of the input power pins. In this
specific case, the lower supply voltage has no effect on the IN1 and IN2 switch on-resistances.
ELECTRICAL CHARACTERISTICS
Over recommended operating junction temperature, VI(IN1) = VI(IN2) = 5.5 V, IO(OUT) = 0 A, and RILIM = 400 Ω, unless otherwise
noted.
