Technical Specifications

Voltage Regulation & Efficiency

The L7805ABV accepts an input voltage of up to 35V and regulates it down to a fixed 5V output. Its dropout voltage is 2V at 1A (Typical), ensuring stable performance even with fluctuating input voltages. The regulator maintains high efficiency with a quiescent current (Iq) of just 6mA, making it ideal for battery-powered applications.

Current Handling & Power Dissipation

Capable of delivering up to 1.5A of continuous output current, the L7805ABV is suitable for powering microcontrollers, sensors, and other low-to-medium power devices. The TO-220 package ensures excellent thermal dissipation, supporting reliable operation under high-load conditions.

Noise Suppression & Stability

With a Power Supply Rejection Ratio (PSRR) of 68dB (120Hz), the L7805ABV effectively filters out input noise, providing a clean and stable 5V output. This feature is critical for sensitive analog and digital circuits.

Advanced Protection Mechanisms

The L7805ABV includes multiple built-in protections to enhance durability: - Over-Temperature Protection (OTP): Shuts down the regulator if excessive heat is detected. - Short-Circuit Protection: Safeguards the IC and connected components in case of output shorts.

Wide Operating Range

Designed for versatility, the L7805ABV operates across a temperature range of -40 C to +125 C, making it suitable for industrial, automotive, and outdoor applications.
