DESCRIPTION
1
SENSE
Allows Kelvin sense of VOUT at the load. (Positive side of the reference
voltage of the device).
2
ADJ
Negative side of the reference voltage for the device. Adding a small
bypass capacitor from the ADJ pin to ground will improve the transient
response.
3VOUT
Power output of the device.
4VCTRL
Supply pin for the control circuitry of the device. The current flow into this
pin will be about 1% of the output current. VCTRL must be between 1.0V
and 1.3V greater than the output voltage for the
device to regulate.
5VIN
Output load current is supplied through this pin. VIN must be between 0.1V
and 0.8V greater than the output voltage for this device to regulate.
