Description
1
EN
Enables the device if connected to Vin and disables the device if forced to gnd.
2
IN
Supply voltage. This pin is connected to the drain of the internal N-mos. Connect this
pin to a capacitor larger than 10µF.
ADJ
–
Connecting this pin to a voltage divider it is possible to programme the output voltage
between 1.2V and 5V.
3
–
OUT Regulated output voltage. This pin is connected to the source of the internal N-mos.
Connect this pin to a capacitor of 10µF.
OUT
–
Regulated output voltage. This pin is connected to the source of the internal N-mos.
Connect this pin to a capacitor of 10µF.
4
–
PGOOD Power good output. The pin is open drain and detects the output voltage. It is forced
low if the output voltage is lower than 90% of the programmed voltage.
5, 6, 7, 8
GND
