The TPS22917LDBVR: It handles 2 A continuous output current across a 0 V to 5.5 V load voltage range, with a 1 V to 5.5 V bias supply. The 220 mOhm typical Rds(on) is specified at 25°C — expect it to rise to roughly 400 mOhm at 125°C junction, so budget the I²R loss at your operating temperature.
Slew rate control and reverse current blocking
Built-in slew rate control limits inrush current during turn-on, reducing supply droop and EMI on the rail. The load discharge feature pulls the output to ground when the switch is disabled, preventing floating loads on shared buses. Reverse current protection blocks back-feed when Vout exceeds Vin — useful in multi-rail sequencing or battery-backup scenarios where the load can hold a higher voltage momentarily.
For 2 A continuous, ensure adequate copper pour on the drain pad to keep junction rise within the SOA.
