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.

Short Circuit Input Current 50mA typ. / 100mA max.
Optional Diode Protection Circuit
Add a blocking diode to Vout if current
can flow backwards into the output, as
this can damage the converter when it
is powered down. Protection diodes are
required for high capacitive loads.
The diode can either be fitted across the
divice, if the source is low impedance
or fitted in series with the output (re-
commended).
