Product Description
 
The UM1450 series are a group of positive voltage output, high precise and low power consumption voltage regulators. The maximum input voltage is 16V. The output voltages are selectable in 100mV steps within a range of 2.5V to 5V. It can also be customized on command.
The UM1450 series have very low power consumption (IQ=2μA) which can greatly improve natural life of batteries.
The UM1450 series are available in a low profile SOT23-3 & SOT89-3 packages, which are lead (Pb)-free.
 
Features
