1

Chip Enable Input (Active high).

GND

2

Ground.

VIN

3

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

the output pin.

VOUT

4

when the device is disabled. Minimum 1μF low ESR ceramic capacitor is required at

FB

5

Feedback Voltage. FB is the non-inverting input to the error amplifier. A resistor

divider from the output to GND is used to set the regulation voltage as

non-inverting input to noisy source to guarantee stable operation.
