The input range is from 2.5 to 5.5VDC for use  8-Pin QFN  arrasy<br>in low power/low voltage systems. The tightly regulated output voltage can be set with two resistors in<br> the range from 0.6V up to 4.3V. The output current is up to 1.2A and is fully protected against<br>Package<br>continuous short-circuits, output overcurrent or over-temperature faults. Its high current and small<br>size make the RPZ-1.2 ideal for optical modules, industrial PCs, machine imaging systems, distributed<br>power architectures, portable equipment in telecom as well as industrial applications.<br>Selection Guide<br>Part Input  Output  Output Efficiency  [(2)]<br>Number Voltage Range Voltage Range [ (1)] Current max. typ.<br>[VDC] [VDC] [mA] [%]<br>RPZ-1.2 2.5 - 5.5 0.6 - 4.3 1200 87<br>RoHS 2+ REACH<br>Notes: compliant10 from 10 compliant<br>Note1: As input approaches output voltage set point, device enters 100% duty cycle mode.
