PIN DESCRIPTION
Pin Number Name Function
1 V
IN
Input supply pin. Bypass this pin with a 1-mF ceramic or tantalum capacitor to ground.
2 GND Ground pin. Local ground for C
BP
and C
OUT
.
3 SD By applying less than 0.4 V to this pin, the device will be turned off. Connect this pin to V
IN
if unused.
4 (Version A) BP
Noise bypass pin. For low noise applications, a 0.1-mF or larger ceramic capacitor should be connected from this pin to
ground.
4 (Version B) FB Connect to divided output voltage to adjust the regulation point.
5 V
OUT
Output voltage. Connect C
OUT
between this pin and ground.
