The R-5XXX series is a high performance 1.2V to 5.0V , 2Amp to 5Amp,12-Pin SIP (single in-line package)
integrated switching regulator (ISR). Synchronuous - rectified design yields excellent efficiencies up to 96%.
Short circuit protection with crowbar function to reduce the short circuit input current to under 50mA. Autosense
function compensates for any losses in long circuit loops.
