C4/RBLDR is a dual purpose pad which is unpopulated by default. A ceramic capacitor (C4) may be used here if extra high frequency
bypassing is desired across the LED load. Alternatively a bleeder resistor (RBLDR) in the range of 10kΩ to 100kΩ may be placed here to
quickly discharge C3 and prevent prolonged LED glow due to the energy stored in C3.
