Description

1

OUT

OUT

Regulated output voltage pin. A small 1

mF ceramic capacitor is needed from this pin to

ground to assure stability.

2

N/C

ADJ

Feedback pin for set−up output voltage. Use resistor divider for voltage selection.

3

GND

GND

Power supply ground. Expose pad must be tied with GND pin. Soldered to the copper

plane allows for effective heat dissipation.

4

EN

EN

Enable pin. Driving EN over 0.9 V turns on the regulator. Driving EN below 0.4 V puts

the regulator into shutdown mode.

5

N/C

N/C

Not connected. This pin can be tied to ground to improve thermal dissipation.

6

IN

IN

Input pin. A small capacitor is needed from this pin to ground to assure stability.
