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 shut-
down, output voltage falls to zero and supply current is reduced to 0.5 µA (max).
Output voltage adjust terminal. Output voltage setting is programmed with a resistor divider
from V_OUT to this input. A capacitor may also be added to this input to reduce output noise
(See Section 3.2, Output Capacitor).
Regulated voltage output.
