The LM317LZ is an adjustable output, three-terminal positive linear voltage regulator. This article mainly introduces circuits, pinout, datasheet and other detailed information about STMicroelectronics LM317LZ.
LM317LZX
The LM317LZ is an adjustable output, three-terminal positive linear voltage regulator. This voltage regulator requires only two external resistors to set the output voltage. The LM317LZ is a monolithic integrated circuit designed for use as positive adjustable voltage regulators in SO-8 and TO-92 packages. It can deliver up to 100 mA of load current and has a 1.2 to 37 V output voltage range. The nominal output voltage is chosen using only a resistive divider, making the device extremely simple to use and removing the need to stock a large number of fixed regulators.

STMicroelectronics, headquartered in Plan-les-Ouates, Switzerland, near Geneva, is a multinational electronics and semiconductors firm. The company was created in 1987 by the merger of two government-owned semiconductor companies: "Thomson Semiconductors" in France and "SGS Microelettronica" in Italy. It is known as "ST" and is the most profitable semiconductor chip producer in Europe. While the corporate headquarters and EMEA regional offices of STMicroelectronics are in Geneva, the holding company, STMicroelectronics N.V., is based in the Netherlands.
The company's US headquarters are located in Coppell, Texas. The headquarters for the Asia-Pacific region is in Singapore, while Japan and Korea's activities are in Tokyo. The company's China regional headquarters are based in Shanghai.
