USB Power SW DIST Single 5.5V 1.53A 5-Pin SOT-23 T/R

The TPS20xxC and TPS20xxC-2 power-distribution switch family is intended for applications such as USB where heavy capacitive loads and short-circuits are likely to be encountered. This family offers multiple devices with fixed current-limit thresholds for applications between 0.5 A and 2 A.The TPS20xxC and TPS20xxC-2 family limits the output current to a safe level by operating in a constant-current mode when the output load exceeds the current-limit threshold. This provides a predictable fault current under all conditions. The fast overload response time eases the burden on the main 5 V supply to provide regulated power when the output is shorted. The power-switch rise and fall times are controlled to minimize current surges during turn-on and turn-off.
