KF80BD-TR Description

Short technical summary and product information.

The STMicroelectronics KF80BD-TR is a linear voltage regulator featuring a fixed 8V output voltage and a maximum output current of 500mA. It offers a very low dropout voltage of 0.7V at 500mA and a low quiescent current, making it suitable for battery-powered systems and low-power applications.

 

This regulator includes internal current and thermal protection features, along with a logic-controlled shutdown function for power saving. It requires a minimal 2.2 µF capacitor for stability. The device operates over a wide temperature range of -40°C to 125°C and is housed in an 8-SOIC surface-mount package.

 

Key electrical characteristics include a typical PSRR of 72dB at 120Hz, decreasing to 60dB at 10kHz. The output accuracy is ±2% at 25°C. The enable pin allows for electronic shutdown, further reducing power consumption when not in use.
