Overview

The UM1770 series are VLDO (very low dropout) linear regulators designed for low power portable applications. Typical output noise is only 90μV_RMS (Fixed Output, V_OUT = 1.0V) and maximum dropout is just 320mV at the load current of 500mA. The internal P-channel MOSFET pass transistor requires no base current, allowing the device to draw only 250μA during normal operation at the maximum load current of 500mA. Other features include high output voltage accuracy, excellent transient response, under voltage lockout, stability with ultra low ESR ceramic capacitors as small as 1μF, short-circuit and thermal overload protection and output current limiting. The UM1770Y-xx series are available in SOT89-5 package and the UM1770DA-xx series are available in a low profile DFN6 2.0×2.0 package.
