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
, causing extra supply current (
I
). To minimize
this current, consider keeping the LED pins at a voltage
equal to or greater than V
DD
.
