General Description
The UM1430/1440 series are high input low quiescent current regulators implemented in CMOS
technology. They can deliver 30mA output current and allow an input voltage as high as 18V.
They are available with several fixed output voltages ranging from 2.0V to 6.0V. CMOS
technology ensures low voltage drop and low quiescent current.
The UM1430 is available in SOT23-3, SOT23-5 and SOT89-3 packages. The UM1440 is
available in SOT23-5 and SOT89-5 packages.
