Designed for serious audio use, the LV-Regulator uses a simple RC filter (1 ohm & 10kµF) as a pre-filter before the LDO regulator and holds bypass capacitors for all the electrolytic capacitors and a 4.7µF/400V polypropylene shunting capacitor at the output. The 1-ohm resistor is a 4W device, so the maximum current output is 2A. The RC filter before the voltage regulator unburdens the regulator from having to deal with sharp transients. The LV-Regulator can be set up as either a 5Vdc or 9Vdc regulator or as a 12Vdc or 18Vdc).
The new board is bigger than the H-PS-1 and no longer can accept the voltage-doubler rectifier configuration. But the PCB accepts two possible rectifier configurations (full-wave bridge and full-wave center-tapped). In other words, this regulator can deliver +5Vdc or +9Vdc from two different power transformer secondary voltages; for example, for 9V output either a 10Vac or 20Vac center-tapped transformer secondary; or 5Vdc from either a 6.3Vac to 9Vac or a 12Vac to 18Vac center-tap secondary.
At idle, without an external load, the regulator draws 10mA of current. The board is 4.5in by 2.2in (114mm by 56mm), with four mounting holes. The kit includes all the parts, diodes, ultra-fast rectifiers, Nichicon and Panasonic capacitors, resistors, LDO regulator and heatsink and heatsink mounting kit, including four aluminum hex standoffs, rubber O-rings, eight screws, and user guide.
