is 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 4.6-36V, 1.5mA ultra- low no load input
current, continuous short-circuit protection, low ripple noise (max.: up to 50mV) and
much more.

SMD
The new 2A series has operating temperature from -40°C to +100°C, meets EN62368
standard (Pending) and delivers efficiencies up to 96%, 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, IoT, medical, mining, railway and other
related industries.
