7850 Voltage Regulator - Simplify Power Control...!
Tharun Electronics stands as a trusted name in welding machine spares, delivering quality electronic components that ensure reliability and efficiency for every application.
The 7850 Voltage Regulator is a part of the famous 78xx series of voltage regulators, widely used in electronic circuits for providing a stable and regulated DC output. The “50” in 7850 indicates a fixed output voltage of 50V DC, making it ideal for high-voltage applications that need consistent and noise-free performance.
🔧 Working Principle
The 7850 voltage regulator converts unregulated DC input (typically 52V–70V) into a steady 50V output. It works on a series pass transistor and feedback mechanism that maintains a constant output regardless of input voltage changes or load variations. Input Voltage Range: 52V to 70V Output Voltage: 50V DC (Fixed) Maximum Output Current: 1A (varies by manufacturer) Type: Linear, Positive Voltage Regulator
