LT3050EDDB Description

The LT3050EDDB from Analog Devices Inc. is a high-performance, low-dropout (LDO) linear voltage regulator designed for precision applications requiring adjustable output voltage. With an input voltage range up to 45V and an adjustable output from 0.6V to 44.5V, this regulator delivers a stable 100mA output current while maintaining excellent line and load regulation. Its ultra-low quiescent current of 90 µA and dropout voltage of 0.55V @ 100mA make it ideal for power-sensitive designs. The device is housed in a compact 12DFN surface-mount package, suitable for space-constrained applications.
