PIN DESCRIPTIONS

The descriptions of the pins are listed in Table 2-1.

Description

Unregulated supply input.

2

GND

Ground terminal.

3

SHDN

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).

4

ADJ

Output voltage adjust terminal. Output voltage setting is programmed with a resistor divider

(See Section 3.2, Output Capacitor).

Regulated voltage output.
