UM1770 VLDO Linear Regulator

UM1770 Description

UM1770 500mA, Micropower, VLDO Linear Regulator UM1770Y-xx SOT89-5 UM1770DA-xx DFN6 2.0×2.0 General .
The UM1770 series are VLDO (very low dropout) linear regulators designed for low power portable applications.

UM1770 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 UM1770

UM1770 Applications

* Typical output noise is only 90μVRMS (Fixed Output, VOUT=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.
