Pin Description
PIN
SOP-8
DESCRIPTION
POK
1
Assert high once VOUT reaches 92% of its rating voltage. Open-drain output.
Enable Input. Pulling this pin below 0.4V turns the regulator off, reducing the quiescent
current to a fraction of its operating value. The device will be enabled if this pin is left
open.
VEN
2
High current input voltage. Large bulk capacitance should be placed closely to this pin .
VIN
3
A 10µF ceramic capacitor is recommended at this pin.
VBIAS
NC
4
5
Input voltage for controlling circuit.
Not connected.
The power output of the device. A pull low resistance exists when deactivate device by
VOUT
6
VEN.
This pin, when grounded, sets the output voltage by the internal feedback resistors. If
external feedback resistors are used , the output voltage will be VOUT=0.8(R1+R2)/R2
Volts.

GND
Reference ground.
