Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
STMicroelectronics LM337K is a negative adjustable linear voltage regulator with a 1.5A output current capability in a TO-3 package. This device offers an adjustable output voltage ranging from -1.2V to -37V, with a maximum input voltage of 40V. Key protection features include over-current and over-temperature shutdown. The regulator exhibits a Power Supply Rejection Ratio (PSRR) between 77dB and 60dB across a 120Hz frequency range. It is designed for through-hole mounting and operates within a temperature range of 0°C to 125°C. The LM337K is commonly utilized in power supply designs for telecommunications equipment, industrial control systems, and consumer electronics requiring stable negative voltage regulation.
