Input supply pin. Bypass this pin with a 1-mF ceramic or tantalum capacitor to ground.
Ground pin. Local ground for C
By applying less than 0.4 V to this pin, the device will be turned off. Connect this pin to V
Noise bypass pin. For low noise applications, a 0.1-mF or larger ceramic capacitor should be connected from this pin to
ground.
Connect to divided output voltage to adjust the regulation point.
