The PSREG is a high quality low voltage regulated power supply. It is recommended for use with solid state preamplifiers, active
crossovers, filters, CD players, and other circuits with low-to-medium current requirements. The PSREG’s voltage can be fixed from
a positive 5 volts to 24 volts by the selection of a few resistors, and its output is capable of supplying up to 1.0 ampere of
current.
The PSREG uses the Linear Technologies LT1085 regulator which is a low
dropout, high efficiency device highly recommended for audio applications. The rectifier diodes are low noise Schottky devices and
filtering is accomplished with the Nichicon super-low impedance electrolytic capacitors. The PSREG is a very compact design
measuring just 2 inches by 2.5 inches with a height of less than 1.5 inches making it very useful for CD player mods.
*** Please specify your desired output voltage ***
Typical outputs available are 5V, 6V, 12V, 15V, 18V, 24V

The following equation can be used to calculate the resistor values required for a specific output
voltage:
Vout = 1.25 ( 1 + R2/R1) + R2 (50 x 10-6)
The table below lists resistor values for several common voltages.
If you order our kit, be sure to specify which voltage you will be using, and we will send you the correct
values.
