Vout: The regulated positive power output with respect to the GND node. GND: This is the common ground connection for the ‘Vin’ and ‘Vout’ power connections. It is also the 0 VDC reference for the ‘Inhibit’ and ‘Vo Adjust’ control inputs. Inhibit: The Inhibit pin is an open-collector/drain negative logic input that is referenced to GND. Applying a low- level ground signal to this input disables the module’s output and turns off the output voltage. When the Inhibit control is active, the input current drawn by the regulator is significantly reduced. If the Inhibit pin is left open- circuit, the module will produce an output whenever a valid input source is applied. Vo Adjust: A 0.1 W 1 % resistor must be directly connected between this pin and the GND pin to set the output voltage to a value higher than 0.9 V. The temperature stability of the resistor should be 100 ppm/°C (or better). The set point range for the output voltage is from 0.9 V to 2.5 V. The resistor required for a given output voltage may be calculated from the following formula. If left open circuit, the output voltage will default to its lowest value. For further information on output voltage adjustment, consult the related application note. Rset = 10 k Ω · 0.891 V – 4.99 k Ω Vout – 0.9 V The specification table gives the preferred resistor values for a number of standard output voltages.
