Based on the design of the flagship linear power supply LPS01EXLE, the design of the differential power supply for analogue, LPS-Differential, and the power supply for digital 5 V systems, LPS-Digital, was initiated.

LPS-Differential

Positive and negative power supply with the filter configuration of the LPS01 intact. It has a maximum output of 1.5 A, but uses the LT1963A/LT3081 combination, which has excellent over-response and can handle up to ±19 V.
The LT1963A has superior over-responsiveness, but has a maximum input of 20 V, which would result in overvoltage when using a 24 V toroidal transformer.
Therefore, an LM317/337 is included as a post-regulator to limit the voltage to 19.5V.
(No post-regulator is used for up to ±12 V).

LPS-Digital

Generally, 5 V for digital use is taken from the + side of the differential power supply with a DC-DC converter or regulator, but to ensure sound quality, it is separated from the toroidal transformer and contained on a single board.
Because a low-noise power supply is required for digital use, this is also designed with the same filter configuration as the LPS01.
The design allows for the optional placement of a USB A or USB Type-C connector, which can also be used as a stand-alone maximum 3 A power supply.

The board is currently being designed, and it will be decided how it will fit into the case, but it will basically be used for embedded or switching power supply devices with internal bypass modifications.

The problem is obtaining the LKG Super Through.
