R-7xxxP_D

Description

The R-7xxx series is a high performance 2.5V to 17V, 2Amp to 4Amp, 12-Pin SIP (single in-line

package), integrated switching regulator (ISR). The synchronous - rectiﬁed design yields excellent

efﬁciencies up to 97%. Short circuit protection reduces the short circuit input current to under 50mA.
