PIN DESCRIPTION
Pin Number Name Function
1 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
2 ERROR The open drain output is an error flag output which goes low when V
OUT
drops 4% below its nominal voltage.
3 V
IN
Input supply pin. Bypass this pin with a 1-mF ceramic or tantalum capacitor to ground
4 V
OUT
Output voltage. Connect C
OUT
between this pin and ground.
5 GND Ground pin. For better thermal capability, directly connected to large ground plane
