LM317LM General Description

LM317LM is a three-terminal adjustable voltage regulator designed to provide a fixed output voltage ranging from 1.25V to 37V with a current output of up to 1.5A. It features internal thermal overload protection and is capable of being used as a constant current regulator with a simple external resistor. The LM317LM operates over a wide input voltage range of 3V to 40V and has a low quiescent current of 2.5mA. It also has a built-in current limiting and thermal shutdown feature to protect the device from excessive current and temperature. This adjustable voltage regulator is commonly used in various applications such as power supplies, battery chargers, and voltage references. It can be easily implemented with only two external resistors to set the output voltage to the desired level. Additionally, the LM317LM is available in a TO-92 package which makes it suitable for high-density applications and is also available in a surface-mount package for easy integration onto circuit boards. It is a versatile and reliable device that offers precise voltage regulation and current limiting capabilities in a compact form factor
