PIN 1: VSBY - Standby supply voltage (5V) input for

3.3V regulator when VCC falls below

4.3V. Some NICs that operate in

“ Wake-On-LAN” mode get a 5V

standby

through

a

cable

that

connects

directly

to

a

specific

header on the Motherboard.

PIN 2: VCC

- Primary supply voltage (5V) input for

3.3V regulator.

PIN 3: VOUT - 3.3V regulated output voltage when

internal low impedance switch.

PIN 4: DRIVE - Signal

for

controlling

external

auxiliary switch .Active Low when

internal regulator is disabled .

PIN 5-8: GND

- Negative reference for all voltages.
