Description
The R-7XXX series is a high performance 2.5V to 15V , 2Amp to 4Amp,12-Pin SIP (single in-line
package), Integrated switching regulator (ISR). The Synchronuous - rectified design yields excellent effi-
ciencies up to 97%. Short circuit protection with crowbar function reduces the short circuit current to
under 50mA of input current.
