The L7805ACV from STMicroelectronics is a classic fixed 5V linear regulator capable of delivering 1.5A. With a typical dropout of 2V at 1A, it requires a minimum input of 7V. The device features internal thermal overload protection and safe-area compensation. Its TO-220 package allows easy mounting on heatsinks for high-power applications. The 6mA quiescent current is acceptable for mains-powered designs.
- High Output Current: 1.5A capability powers multiple digital and analog loads.
- Excellent Ripple Rejection: 68dB at 120Hz ensures clean DC for sensitive circuits.
- Robust Protection: Internal thermal shutdown and short-circuit protection enhance reliability.
- Wide Input Range: Accepts 7V to 35V, making it versatile for various supply rails.
Industrial Control Systems
The 5V rail powers PLCs and microcontrollers. The 1.5A output handles multiple logic ICs, while the 68dB PSRR at 120Hz rejects rectifier ripple.
Bench Power Supplies
As a post-regulator after a transformer/rectifier, the L7805ACV provides a stable 5V reference for analog circuits. The TO-220 package with heatsink supports continuous 1.5A.
Automotive Electronics
Regulates vehicle battery (12V) down to 5V for sensors and ECUs. The wide input range tolerates load-dump transients up to 35V.
Audio Equipment
Clean 5V supply for op-amps and DACs. The 68dB ripple rejection minimizes hum in sensitive audio paths.
Home Appliances
Provides regulated 5V for touch panels and display drivers in washing machines and microwaves. The robust TO-220 package withstands thermal cycling.
Test & Measurement
Stable reference for multimeters and oscilloscopes. The low output noise and high PSRR ensure accurate readings.
