7805 Voltage regulator IC
7805 Voltage Regulator IC - 5V 1.5A Fixed Output Linear Regulator (TO-220)
The 7805 is the industry-standard fixed +5V linear voltage regulator IC in a TO-220 package, capable of delivering up to 1.5A of regulated output. Ideal for powering microcontrollers (Arduino, ATmega, PIC), logic circuits, sensors, and any 5V system from higher voltage sources. Available at The Tech Depot, Bengaluru - fast shipping, authentic components, and dedicated technical support.
Key Features
- Fixed +5V Regulated Output: Stable 5.0V DC output with +/-4% tolerance under varying load and input conditions.
- Wide Input Voltage Range: Accepts 7V to 35V DC input (recommended 7V-12V for optimal efficiency and minimal heat).
- Output Current up to 1.5A: Sufficient to power Arduino boards, relay modules, sensor arrays, and small motor drivers.
- Built-in Protection: Internal thermal overload protection, short-circuit current limiting, and safe operating area (SOA) protection.
- TO-220 Package: Industry-standard 3-pin through-hole package; easy to mount with or without a heatsink.
- Low Output Noise: Clean regulated output suitable for analog circuits, ADC reference supplies, and noise-sensitive applications.
- Drop-in Replacement: Pin-compatible with LM7805, L7805CV, MC7805, KA7805, and UA7805 from all major manufacturers.
