Description
UM1650 UM1750 350mA, Micropower, Very Low Dropout Linear Regulator UM1650S-xx SOT23-3 UM1750S-xx SOT23-5 UM1750Y-xx SOT89-5 UM1750DA-xx DFN6 2.0×2.0 .
The UM1650/UM1750 series are very low dropout linear regulators designed for low power portable applications.
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
Applications
* Typical output noise is only 195μVRMS and 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 contr
