VIN

Input voltage

4

VCTRL

Input voltage for controlling circuit

5

NC

Not connected

6

VOUT

Regulated output voltage

7

ADJ

Internal Mode

ADJ is connected to ground. The output voltage is set by internal resistors

External Mode

ADJ is connected to external feedback resistors. The output voltage will be VOUT = 0.6 (R1+R2)/R2.

Do not program below 0.6V

8

GND

Ground

Thermal Pad

GND or Open

The pad may be grounded or left open. This does not replace the need for ground on Pin 8.
