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.

Notes:
1. Requires a 100µF electrolytic or tantalum output capacitor for proper operation in all applications (the capacitor to be placed as close as possible to the output pins).
2. ON / OFF pin driven by TTL (logic gate), open-collector bipolar transistor or open-drain MOSFET.

Add a blocking diode to
Vout if current can flow
backwards into the out-
put, as this can damage
