Negative voltage Regulator 7905 5V 1.5A TO-3
The Negative Voltage Regulator 7905 5V 1.5A TO-3, also known as TO-204AA, is a robust three‑terminal fixed negative voltage regulator designed to provide a steady –5V DC output with a continuous current capacity of up to 1.5A when operated within its specified conditions. Part of the L79xxC family of negative linear regulators, the 7905 is engineered for applications where a reliable negative supply rail is necessary, eliminating distribution issues that can arise from distant central regulation systems and improving local on‑card power stability. Its metal TO‑3 package, also known as TO-204AA, offers excellent heat dissipation, making it suitable for higher load conditions where thermal performance is critical.
Features:
- Provides fixed -5V output voltage.
