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 VOUT 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.
