General Description

The UM1650/UM1750 series are very low dropout linear regulators designed for low power

portable applications. Typical output noise is only 195μV_RMSand maximum dropout is just

110mV(Typ) at the load current of 150mA.The internal P-channel MOSFET pass transistor

requires no base current, allowing the device to draw only 190μA during normal operation at the

maximum load current of 350mA.With a shutdown control pin, the UM1750 consumes less than

1μA current in shutdown mode.

Other features include high output voltage accuracy, excellent transient response, under voltage

lockout, stability with ultralow ESR ceramic capacitors as small as 1μF, short-circuit and thermal

overload protection and output current limiting.

The UM1650 series are available in a low profile SOT23-3 package. The UM1750 series are

available in low profile SOT23-5, SOT89-5 and DFN6 2.0×2.0 packages.
