LT3090HMSE#PBF

LT3090 is a low dropout negative linear regulator. It is easily parallelable to increase output current or spread heat on surface mounted boards. Designed with a precision current reference followed by a high performance rail-to-rail voltage buffer, this regulator finds use in applications requiring precision output, high current with no heat sink, output adjustability to zero and low dropout voltage. This device can also be configured as a 3-terminal floating regulator. It is widely used in application such as post regulator for switching supplies, low noise instrumentation and RF supplies, rugged industrial supplies, precision power supplies etc.
