L7805ACV ST Linear

The L7805ACV from STMicroelectronics is a rugged 5V, 1.5A linear voltage regulator, perfect for generating a stable supply from an unregulated DC source. For selection, its key strengths are a wide 35V maximum input, a guaranteed 5V output at ±2% accuracy, and robust built-in protections against short circuits and thermal overload. The 2V typical dropout voltage suits step-down from mid-voltage rails. High 68dB ripple rejection at 120Hz ensures clean DC, crucial for audio and analog circuits. The TO-220 through-hole package allows direct heatsink mounting for high dissipation. In application, it is the standard building block for powering logic, microcontrollers, and sensors in industrial controls, bench supplies, and white goods. It provides post-regulation after switching converters to reduce noise in audio preamplifiers, 3D printer control boards, and measurement instruments. Its simplicity and reliability make it ideal for any application requiring a fuss-free, protected 5V rail. In stock at HL Electronics – request a quote for fast delivery.
