AMSR2-783.3JZ

AMSR2-78JZ DC-DC Switching Regulator Click to ORDER AMSR2-78JZ samples Aimtec introduces the new AMSR2-78JZ, a 2A Switching Regulator which is designed to be a plug and play alternative to the traditional 78xx series three-terminal linear regulators. The series features an ultra-wide input voltage range of 6-36V, 0.1mA ultralow no load input current, continuous short-circuit protection, low ripple noise (typ.: 30mV) and much more. The new 2A series has operating temperature from -40°C to +85°C, meets EN62368 standard (Pending) and has delivers efficiencies up to 95%, eliminating the need for a heat sink and cutting additional design space and installation cost. This series is suitable for use in applications such as industrial controls, medical, mining, railway and other related industries.
