Dual Linear Power Supply Module LT3042 5V / 3.3V 1A

Module d'alimentation linéaire double 2x A1930 5V 1A

This linear power supply module with two outputs is based on an LT3042 and a pair of high-performance A1930 transistors from Toshiba. It benefits from the PSRR architecture dedicated to the power supply of devices that are very sensitive to noise. It is one of the LTC power supply modules well known for their very low noise level. Its construction incorporates a precision voltage reference with a high performance voltage buffer. It can therefore be connected in parallel to further reduce noise, increase output current and split heat sources to avoid hot spots. It can provide a 5V and 3.3V output voltage while maintaining a minimum noise level. It will therefore be recommended to do everything to power all 5V and 3.3V 1A modules, like the USB XMOS / SPDIF interfaces. This power supply module is stable thanks to a Nover 6800µF capacitor.

Pratique et fonctionnel
Utilisé pour alimenter sur des consomation de moins de 500 mA avec un transfo 2x6v c'est parfait et effectivement très propre à l'écoute

5V extra
Je ne pensais pas améliorer autant le rendu de mon interface Matrix SPDIF 2 (alimentée par le 5V USB) . C'est fait grâce au 5V du LT3042 qui produit un gain en définition, précision, spatialisation, la scène sonore gagne sur tous ces plans.
Dans l’idéal, pourquoi pas une alim 5V/9V?
Quoiqu'il en soit bravo pour cette alim très faible bruit à un prix imbattable .

5V input not enough
I tried it, power seems stable and appears to be low-noise. However, the range provided as input range is wrong, 5V won't be enough to power it, so keep looking if you want to feed it from e.g. USB ports. It worked well using 9V.
