The N-Channel internal switches handle up to 1.25 A continuous, covering the current budget of a typical handheld or mobile device main rail. The 55 µA quiescent current keeps the battery drain low when the device is in standby or off. ## Switching timing and load budget Turn-on delay is 1 ms; turn-off takes 5 ms. That asymmetry matters when the switch transitions between sources: the 5 ms off-delay means the output rail stays live long enough for the downstream regulator input caps to hold up during the switchover, preventing a brown-out on the load. The 1.25 A current ceiling is the absolute maximum the internal FETs can pass. For production designs, derate by 20–30 % depending on ambient temperature and PCB copper area under the 8-TSSOP package — the 4.40 mm-wide body limits thermal dissipation compared to a larger SOIC footprint. That qualifies the part for outdoor handheld terminals, factory-floor mobile scanners, automotive cabin electronics, and any battery-powered device that sees seasonal temperature swings or direct sunlight. The 8-TSSOP package (0.173\" body width, 4.40 mm) is a surface-mount footprint common to low-power analog and power-path ICs. New designs can commit this part to the BOM without a bridge-buy or obsolescence contingency.","metaTitle":"TPS2113APW Source Selector Switch, 2.8V-5.5V, 1.25A, 8-TSSOP","metaDescription":"TI TPS2113APW source selector switch, 2.8V-5.5V supply, 1.25A max output, 55µA quiescent, -40°C to 85°C, 8-TSSOP.
