Description

The MST50AXXB series is an ultra-small, low dropout (LDO) linear regulator that can source 500mA of output current.The MST50AXXB

has fast response to input voltage transient and load current transient, and ensures no overshoot voltage during MST50AXXB  startup 

and short circuit recovery.

The MST50AXXB series has thermal shutdown, current limit, and short circuit protections for added safety.

The MST50AXXB series contains eight fixed output voltages of 1.2V, 1.5V, 1.8V, 2.5V，2.8V, 3.0V, 3.3V, 3.6V.
