LINEAR TECHNOLOGY LT3090EMSE#PBF 电压稳压器, LDO, 可调, -36V至-1.5V输入, 300mV压差, -32V至0V/0.6A输出, MSOP-12
The is a 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. It features fast transient response, high PSRR and output noise as low as 18µVRMS. It generates a wide output voltage range while maintaining unity gain operation. This yields virtually constant bandwidth, load regulation, PSRR and noise, regardless of the programmed output voltage. It 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 precision programmable current limit.
