LT3090 and LT3091 Negative Linear Regulators

Analog Devices Inc. LT3090 and LT3091 Negative Linear Regulators increase output current or spread heat on surface-mounted boards. The LT3090 and LT3091 are designed with a precision current reference followed by a high-performance rail-to-rail voltage buffer. The regulators are used in applications requiring precision output, high current with no heat sink, output adjustability to zero, and low dropout voltage. The Analog Devices LT3090 and LT3091 Negative Linear Regulators can also be configured as a 3-terminal floating regulator.
