The LM337KCSE3 from Texas Instruments is an adjustable 3-terminal negative voltage regulator. It is designed to supply currents in excess of 1.5A over an input voltage range of -3V to -40V. The output voltage can be adjusted from -1.2V to -37V using a simple external resistor divider.
Key electrical specifications include a maximum output current of 1.5A and a PSRR of 77dB at 120Hz. Protection features include over-temperature and short-circuit protection, ensuring reliable operation. The device operates within a temperature range of 0°C to 125°C.
This regulator is housed in a TO-220-3 package, suitable for through-hole mounting. It is a direct replacement for industry-standard LM237 and LM337 regulators, offering consistent performance over temperature.
Applications for the LM337KCSE3 include adjustable power supplies, battery chargers, and active voltage and current regulators where a negative voltage output is required.
