Regulator-5v
About the Regulator-5v PCB
Regulator-5v is an open source PCB design by carr-james, published on GitHub. It is a 2-layer board, with 9 components from 5 distinct parts.
Other key parts include the LP2950-5.0. By type, the board carries 5 capacitors, 2 diodes, 1 IC and 1 resistor.
It belongs with the audio designs in this gallery.
From the project
Reusable Eurorack circuit blocks (KiCad 10 design blocks) and house design rules
Makes a +5V logic rail from +12VA, and holds it down when a jack pushes current back into it.
U1 regulates +12VA to +5V. C1 and C2 hold the input and output. C3 handles high frequency. R1 keeps a minimum load on the rail. D1 clamps the rail if something pushes it above +5.6V.
The Eurorack bus header carries no +5V, so any module with CMOS logic needs this block.
