PIN FUNCTION DESCRIPTIONS
Pin #
Pin Name
Function
Description
1
V
in
Powers the IC
A positive voltage up to 12 V can be applied upon this pin.
2
GND
The IC’s ground
3
ON/OFF
Shuts or wakesup
the IC
A 900 mV level on this pin is sufficient to start the IC. A 150 mV shuts it down.
4
NC
None
It makes no arm to connect the pin to a known potential, like in a pintopin
replacement case.
5
V
out
Delivers the output
voltage
This pin requires a 1.0 F output capacitor to be stable.
