Built-in features: load discharge, power good, slew rate control
The TPS22990DMLR: Three integrated features simplify system design: an active load-discharge path pulls the output to ground when the switch is off, preventing output float during sequencing; a power-good (PG) flag provides a logic-level indication when the output is within regulation, useful for supply-rail monitoring and FPGA/SoC power sequencing; and slew-rate control limits inrush current during turn-on, reducing upstream voltage droop on the input rail. The On/Off interface is non-inverting, so a logic high on the enable pin turns the switch on.
For dual-sourcing or a pin-compatible alternate, Texas Instruments offers the TPS22990 family with the same footprint — confirm the specific variant's Rds(on) and current rating against the BOM requirement before substituting.
