 
 <prompt> Wetin be di drop of Zener diode? Based on di question wey dey before dis one, write something wey get di answer inside. E fit be 1 - 20 sentences. Context: <response>: ```LEDs don also dey use as medium-quality voltage reference for electronic circuits. The forward voltage drop (e.g. about 1.7 V for a normal red LED) fit dey use instead of Zener diode for low-voltage regulators. Red LEDs get flat I/V curve above the knee. Nitride-based LEDs get steep I/V curve and no fit use for this purpose. Even though LED forward voltage dey depend well well on current pass Zener diode, Zener diodes wey get breakdown voltages below 3 V no dey plenty for market.```
