The LT3094IDD#PBF is a linear regulator LDO from Analog Devices, offering an output voltage range of -20V, with a 500mA current rating and ultra-low noise and ultra-high PSRR features. This part also includes an integrated EMI filter, enabling operation in noisy environments. It features very high PSRR and ultra-low noise performance with low 40µA quiescent current, making it suitable for powering sensitive signal-handling circuitry. The combination of fast transient response, high accuracy, and excellent line/load rejection, makes this device an ideal choice for precision audio and RF applications. Its low noise output makes it suitable for a wide range of filtering and other similar applications.
