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 efficien-
cies up to 96%.Short circuit protection with crowbar function to reduce the short current under 50mA
of input current.Autosense function compensates for any losses in long circuit loops.
