PIN 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.
3. VOUT = Power output of the device.
4. VCTRL = 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.
5. VIN = Output load current is supplied through this pin. VIN must be between 0.1V and 0.8V greater
than the output voltage for the device to regulate.
