Pin Description
1
GND
Ground pin. This pin must be connected to ground plane using a low inductance short connection.
2
Vout
The output of the regulator. This pin is also connected to the tab of the package. An output capacitor
must be connected to this pin to insure stability of the regulator.
3
Vin
Input pin of the regulator. Typically a large storage capacitor is connected from this pin to ground to
insure that the input voltage does not sag below the minimum dropout voltage during the load transient
response. This pin must always be 1.3V higher than Vout in order for the device to regulate properly.
