Typical HV Linear Regulator Circuit
• The two graphs below represent the
relationship between output voltage and
LED current with different values of Rs.
• Output voltage is found by the following

formula:
VOUT = VIN - {[IOUT + (ILED * Gain)] * RS}
RLOAD
• Select resistor value to optimize circuit
for VOUT and IOUT range.
