The LT
The LT3090 is a 600mA, low dropout negative linear regulator designed for precision output applications. It features a high performance rail-to-rail voltage buffer and can be easily paralleled to increase output current or spread heat on surface mounted boards.
Key specifications include a wide input voltage range of -1.5V to -36V and an output voltage range from 0V to -32V. The device offers low output noise (18µVRMS) and is stable with ceramic, tantalum, or electrolytic capacitors. It includes built-in protection features such as reverse output protection, internal current limit with fold-back, and thermal shutdown.
