The AM1SR-0503SJZ is a miniature, wide input range, step down, switching regulator from Aimtec. This component is designed for applications operating between 4.5 to 75V and provides up to 500mA of output current. It features built-in protections such as over-voltage, over-temperature, 2.5V pre-biased start-up, and short-circuit protection, as well as a switch-over or “hiccup” mode for output overload protection during extreme overload or low input voltage conditions. This component is designed to remain in an active-mode when the output is short-circuited, thereby maintaining system performance, reliability and safety. It is MSL3 rated and is available in a SIP wide-footprint package.
