Low Noise LDO Voltage Regulator +15V

Sigma78 Régulateur de tension LDO faible bruit +15V

This low noise LDO voltage regulator Sigma78 (S78) can advantageously replace a LM7815 regulator (the pinout is the same). It has an output voltage of +15V DC with a 4µV ripple. This model is developed on the basis of the LDO TI TPS7A 4701RGW regulator. Its maximum input voltage is 35V and its maximum output current is 1A.

It is recommended that the difference between input and output voltage is not less than 0.5V and the current is not more than 0.7A. Make sure that you have sufficient heat dissipation, especially when the voltage difference is high.

Régulateur haut de gamme
Les régulateurs positifs et négatif de cette gamme ont plusieurs avantages. Bien sûr le bruit est 10 fois plus bas qu'un 78xx
Mais contrairement à d'autres régulateurs discrets qui sont plus larges, il fait la même taille qu'un 78xx. Ce qui fait que l'on peut remplacer les régulateurs de matériel existant, en lieu est place.
D'autre part, sa tension d'entrée est aussi de 35V comme les 78xx, et non pas 20V comme d'autres régulateurs.
J'ai remplacé les 78xx et 79xx de mon lecteur réseau. Aucun problème. J'avais essayé d'autres régulateurs discrets qui apportaient une réelle coloration. A la mesure, ça s'appelle du bruit.
Donc pour ces modèles, pas de problème. C'est ce que je mettrai pour alimenter le buffer de mon futur classe D
