LT3083ET in Linear Tech / ADI LT Series Family
The LT3083ET is a high-performance 3A low dropout (LDO) linear regulator from Analog Devices (formerly Linear Technology). Utilizing a unique architecture based on a precision current source and voltage follower, it allows for easy paralleling to increase output current and spread heat. It is primarily used in applications requiring high current, low noise, and the ability to adjust output voltage down to 0V without the need for external resistor dividers.
Variants in This Sub-Family
Variants within the LT3083 sub-family primarily differ by package type and lead finish. The ET suffix specifically denotes the 5-lead TO-220 plastic package, which is optimized for through-hole mounting and heat sink attachment. While the internal silicon remains consistent across the series, other variants like the LT3083IQ or LT3083MP offer different temperature grades and surface-mount packaging options such as DD-PAK or DFN.
