The switch is non-inverting and driven by a logic-level On/Off input. Listed as Active in the product lifecycle, the TPS2051ADG4 carries no imminent end-of-life notice.","metaTitle":"TPS2051ADG4 High-Side Power Switch, 80 mOhm, 500 mA, Active","metaDescription":"Texas Instruments TPS2051ADG4 high-side power switch, 80 mOhm Rds(on) typ, 500 mA output, 2.7V–5.5V load.
