Analog Devices LT3078
The LT3078 is ideal for powering highperformance FPGAs, data converters, RF, and all noisesensitive signal chain applications. The output voltage is digitally selectable in 50mV increments from 0.5V to 1.2V, 100mV increments from 1.2V to 1.8V, and discrete levels at 2V, 2.5V, 3V, 3.3V, and 4.2V. The LT3078’s unity-gain operation provides virtually constant output noise, PSRR, and bandwidth independent of the programmed output voltage.| Part No. | LT3078 |
