Pin Function

VIN

8

Input Voltage. This is the source input to the power device that supplies

current to the output pin.

GND

4

Ground.

EN

5

Chip Enable Input (Active high).

VO

1

Output Voltage. VOUT is power output pin. An internal pull low resistance

exists when the device is disabled. Minimum 4.7uF low ESR ceramic

capacitor is required at this pin for stabilizing VOUT voltage.

NC

2,6

No Connection.

PG

7

Open Drain Power Good Indicator

ADJ

3

Feedback. Error amplifier input. This pin should be connected to external

resistive divider from output voltage.
