PME02-SERIES

ꢀ 500 mA Switching Regulator

ꢀ Wide Input

Rev.09-2009

The PME02-500mA Series with high efficiency switching regulators are

ideally supply for space constrained mobile applications. They are no need

for any heat sinks, even if operate at +85°C. The additional features include

remote ON/OFF control and adjustable output voltage. Super low ripple and

noise of typically only 10mV and a shutdown input current of typically only

15uA.
