STMicroelectronics L4938NPD is a dual positive linear voltage regulator IC. This device offers a fixed 5V output and a tracking adjustable output capable of sourcing up to 500mA, with a secondary output at 50mA. Designed for robust operation, it features over-temperature and short-circuit protection. The L4938NPD includes enable and reset control functions, enhancing system management. With a maximum input voltage of 25V and low dropout voltages of 0.4V at 50mA and 0.6V at 500mA, it is suitable for applications requiring efficient power regulation. The component is housed in a 20-SOIC (PowerSO-20) package with an exposed pad for improved thermal performance, suitable for surface mounting. This regulator finds utility in automotive and industrial control systems.
