The LM317BT from STMicroelectronics is a versatile adjustable positive voltage regulator. It is designed to supply currents in excess of 1.5A over an output voltage range of 1.2V to 37V. This regulator is easy to use, requiring only two external resistors to set the output voltage.
Key features include internal current limiting, thermal shutdown, and safe area compensation, making it highly reliable and essentially blow-out proof. The device operates within a temperature range of -40°C to 125°C and has a typical PSRR of 80dB at 120Hz.
This adjustable regulator is suitable for a wide variety of applications, including local on-card regulation and programmable output regulators. It can also be configured as a precision current regulator by connecting a fixed resistor between the adjustment and output pins. The LM317BT is available in a through-hole TO-220-3 package, facilitating easy integration into circuit designs.
The device is Pb-free and Halogen-free, aligning with environmental compliance standards. Its robust design and adjustable nature make it a flexible choice for power management solutions.
