Product Description
 
The UM153xx/UM154xx series are ultra low quiescent current low dropout linear regulators designed for low power portable applications. The range of output voltage is from 1.3V to 5.0V while operated from 2.2V to 5.5V input. The EN function of UM154xx can disable the entire circuit by inputting low level signal.
The UM153xx/UM154xx series offer high output voltage accuracy, excellent transient response, stability with ultra low ESR ceramic capacitors as small as 1μF, thermal overload protection and output current limiting. The UM153xx is available in a low profile SOT23-3 or SOT89-3 package. The UM154xx is available in a low profile SOT23-5, SOT89-5 or DFN6L 2.0×2.0 package.
