Description
Unregulated supply input.
Ground terminal.
Shutdown control input. The regulator is fully enabled when a logic high is applied to this
input. The regulator enters shutdown when a logic low is applied to this input. During
shutdown, output voltage falls to zero, ERROR is open circuited and supply current is
reduced to 0.5µA (max).
Out-of-Regulation Flag. (Open drain output). This output goes low when V_OUT is out-of-
tolerance by approximately – 5%.
Regulated voltage output.
