Description

General part information

LT3090 Series

The LT3090 is a 600mA, low dropout negative linear regulator that 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. The device can also be configured as a 3-terminal floating regulator.The LT3090 features fast transient response, high PSRR and output noise as low as 18μVRMS. The LT3090 generates a wide output voltage range (0V to –32V) while maintaining unity gain operation. This yields virtually constant bandwidth, load regulation, PSRR and noise, regardless of the programmed output voltage.The LT3090 supplies 600mA at a typical dropout voltage of 300mV. Operating quiescent current is nominally 1mA and drops to << 1μA in shutdown. A single resistor adjusts the LT3090’s precision programmable current limit. The LT3090’s positive or negative current monitor either sources a current (0.5mA/A) or sinks a current (1mA/A) proportional to output current. Built-in protection includes reverse output protection, internal current limit with foldback and thermal shutdown with hysteresis.ApplicationsPost Regulator for Switching SuppliesLow Noise Instrumentation and RF SuppliesRugged Industrial SuppliesPrecision Power Supplies
