Application circuit: Output voltage
V
Q higher than reference voltage VREF (version GA / EJ A
only)
For output voltages higher than the reference voltage, the voltage divider has to be applied between the feedback
(version GA / EJ A only). The equation for the output voltage with respect to the reference voltage is given by:
Keep in mind that the input voltage has to be at minimum equal to the output voltage plus the dropout voltage of
the regulator.
With a given reference voltage
V
REF, the desired output voltage VQ and the resistor value R1FB, the resistor value
for
