Pin Description
Pin Number
Pin Name
Pin Function
1,12
SW
Switch (Output): Internal power P-Channel MOSFET output switch
2,11
VIN
Supply Voltage (Input): Supply voltage for the source of the internal P-channel
MOSFET and driver.
Requires bypass capacitor to GND.
3,10
PGND
Power Ground. Provides the ground return path for the high-side drive current.
4
SGND
Signal (Analog) Ground. Provides return path for control circuitry and internal
reference.
5
BIAS
Internal circuit bias supply. Must be bypassed with a 0.1uF ceramic capacitor to
SGND.
6
FB
Feedback. Input to the error amplifier, connect to the external resistor divider
network to set the output voltage.
7
NC
No Connect. Not internally connected to die. This pin can be tied to any other pin
if desired.
8
EN
Enable (Input). Logic level low will shutdown the device, reducing the current
draw to less than 5uA.
9
PGOOD
Power Good. Open drain output that is pulled to ground when the output voltage
is outside +/- 7.5% of the set regulation voltage
EP
GND
Connect to ground.
