LM317LZ Description

Short technical summary and product information.

The LM317LZ from STMicroelectronics is a versatile, adjustable positive linear voltage regulator. It is designed to supply output currents in excess of 100 mA over an output voltage range of 1.2 V to 37 V. This regulator is exceptionally easy to use, requiring only two external resistors to set the output voltage. Its internal circuitry includes current limiting, thermal shutdown, and safe area compensation, making it highly reliable.

 

The LM317LZ is suitable for a wide variety of applications, including local on-card regulation. It can also be configured as a programmable output regulator or a precision current regulator by connecting a fixed resistor between the adjustment and output pins. The device is available in a standard TO-92-3 package, suitable for through-hole mounting.

 

Key electrical characteristics include a maximum input voltage of 40V, a typical dropout voltage of 3V, and a power supply rejection ratio (PSRR) ranging from 65dB to 80dB at 120Hz. The operating temperature range is from 0°C to 125°C. Protection features include over current, over temperature, and short circuit protection.
