Low noise power supply

• 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.

• The output voltages can be set via a resistor.
• The supply can be turned on or off via a switch, but you could also solder a TTL signal to it.

• Noise performance has not been tested yet!

• Schematic and PCB were drawn August 2021

• Not implemented yet. Not tested yet.

• It's best to read the datasheet for the LT3045 to understand what was done here. The LT3094 is essentially the negative version of it, with no additional features.
• The turning on/off function was implemented using a mechanical switch.
• The current limiting function was implemented by a fixed SMD resistor.
• Thermal stuff was considered by placing the parts close to an solid metal block that is supposed to be fixed to the casing.
