An enable pin allows external on/off control; a soft-start circuit limits inrush current during power-up. The current limit is foldback-type — it reduces output current under short-circuit conditions rather than latching off. ## Temperature grade and operating range Rated for junction temperature from -40°C to 125°C. That covers automotive under-hood, industrial enclosures near motors, and outdoor telecom gear. Input voltage range goes up to 6V, so it can run off a 5V rail or a single Li-ion cell without a pre-regulator. ## Lifecycle and sourcing Active lifecycle status from TI. ROHS3 compliant. No direct second-source alternate is recorded.","metaTitle":"TPS7A2028PDQNRM3 LDO Regulator, 2.8V Fixed, 300mA, 4-X2SON","metaDescription":"TI TPS7A2028PDQNRM3 LDO regulator: 2.8V fixed output, 300mA, 15µA Iq, 0.14V dropout at full load, PSRR 65dB–40dB (100Hz–1MHz).
