The LT3091IFE#PBF is an adjustable output low dropout (LDO) negative linear regulator with programmable current limit in 16 pin TSSOP package. This device can be easily paralleled to increase output current or spread heat on surface mounted boards. It is designed with a precision current reference followed by high performance rail to rail voltage buffer. The LT3091 is used in applications requiring precision output, high current with no heatsink, output is adjustable to zero and low dropout voltage. It has fast transient response, high PSRR and output noise as low as 18μVrms. The operating quiescent current is nominally 1.2mA and drops to less than 1μA in shutdown mode. The device has positive or negative current monitor which either sources a current (0.25mA/A) or sinks a current (0.5mA/A) proportional to output current. It has inbuilt reverse output protection, internal current limit with foldback and thermal shutdown with hysteresis.
