PCB multi-voltage regulator


  1. 19 May 2012

 

A pcb to provide several low-noise voltage has been realized.

Taking as input two power lines at +9 and -9 V, the board is able to give as output single-ended six voltages at +7.5, +7, +6, +5, -7, -7.5 V. The core of the board consisting of 6 low noise regulators which work in order to yield the required output voltages with sufficiently currents to drive different kind of electronic devices.

Below I put the images, the schematics and the relative information files.
