UM4750

UM4750 300mA, Micropower, Dual Channel VLDO Linear Regulator UM4750S-xx SOT23-6 UM4750DA-xx DFN6 2.0×2.0 UM4750DB-xx DFN8 3.0×3.0 General Description The UM4750 series are dual channel VLDO (very low dropout) linear regulators designed for low power portable applications. The range of output voltage is from 1.2V to 5.0V while operated from 2.5V to 5.5V input. Typical output noise is only 200μVRMS and maximum dropout is just 200mV at the load current of 100mA. The UM4750 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 UM4750S-xx series are available in a low profile SOT23-6 package, the UM4750DA-xx series are available in a low profile DFN6 2.0×2.0 package, and UM4750DB-xx series are available in a low profile DFN8 3.0×3.0 package.
