Application Notes (Continued)

REDUCING I

Q WHEN LEDS ARE OFF

In many applications, the LEDs and the LP3944 share the

same V

DD, as shown in Section Typical Application Circuit.

When the LEDs are off, the LED pins are at a lower potential

than V

DD, causing extra supply current (

∆I

Q). To minimize

this current, consider keeping the LED pins at a voltage

equal to or greater than V

DD.
