Categories: Linear, Low Drop Out (LDO) Regulators
Quality Control: Learn More
The STMicroelectronics L4937N is a dual 5V positive linear voltage regulator, available in a 7-HEPTAWATT package. This component offers two distinct outputs: a primary 500mA regulator and a secondary 50mA regulator, both fixed at 5V. Key features include an enable input for controlling the regulator's operation and a reset output function. Protection mechanisms are integrated, providing over-temperature and short-circuit protection. The device operates with an input voltage of up to 25V and exhibits a low dropout voltage of 0.4V at 50mA and 0.6V at 500mA. Operating temperature range is -40°C to 125°C. The L4937N finds application in automotive systems, telecommunications infrastructure, and industrial control equipment.
