* This PCB is a power supply board based on the ICs LT3045 and LT3094, that are low-noise voltage controller, i.e. low-noise alternatives to the commonly used 7815 and 7915 parts. Output voltages are set by a resistor, up to +15 and -19 V. | * This PCB is a power supply board based on the ICs LT3045 and LT3094, that are low-noise voltage controller, i.e. low-noise alternatives to the commonly used 7815 and 7915 parts.
