The WNM4009-3/TR with SOT-23 MOSFETs ROHS by Will Semiconductor is a high-performance, low-dropout linear regulator designed for powering low-power digital circuits. It uses an integrated MOSFET, which eliminates the need for an external Schottky or diode, reducing application size, complexity, and cost. This regulator provides excellent line/load regulation and has both current-limit and overload protection. It uses a 3.3V SOT-23 MOSFET, allowing for optimal performance at low-voltage operation, high-efficient switching and thermal performance. The device is ROHS compliant and RoHS compliant with EUDir 2002/95/EC, providing a reliable and safe choice for applications in various industries.
