For a 3.3V rail feeding an analog front-end, that level of ripple attenuation keeps the output clean. The operating temperature range spans -40°C to 125°C, so it handles the thermal extremes of an outdoor telecom enclosure or the ambient heat inside a motor-drive cabinet without derating concerns. ## Protection and control — built-in safeguards On-chip protection covers over-current, over-temperature, reverse polarity, and under-voltage lockout (UVLO). The reverse-polarity protection is a practical feature for field installations where the input supply leads might get swapped; it saves the regulator and downstream components from damage. UVLO keeps the output off until the input voltage is high enough to maintain regulation, preventing brownout conditions on the load. An enable pin gives you a logic-level shutdown for sequencing or low-power standby. Quiescent current is 200 µA typical, which is modest for a 3A-rated LDO. In always-on systems where the regulator is idling between load events, that Iq adds up — but it's not a primary concern for a fixed-rail industrial supply. ## Through-hole package — board-level fit The TO-220-5 package is a through-hole power package with a metal tab for heatsinking. It suits designs where you want to bolt the regulator to a chassis or heatsink for thermal management at 3A continuous. The five-pin layout is standard for this class of LDO, and the tab is typically connected to ground or the output — verify the pinout against your PCB footprint before layout, as the tab connection varies by manufacturer. ## Lifecycle and compliance The TPS75833KCG3 is listed as Active in production, with ROHS3 compliance. No last-time-buy or obsolescence notice is associated with this part.","metaTitle":"TPS75833KCG3 3.3V 3A LDO Regulator, TO-220-5, Active","metaDescription":"Texas Instruments TPS75833KCG3 fixed 3.3V output LDO, 3A, 0.3V dropout max, 62dB PSRR at 100Hz, -40°C to 125°C.
