Frequently Asked Questions
How accurate is the LM336B grade?
The LM336B (B grade) provides ±1% initial accuracy at 25°C, meaning the output is 2.490V to 2.510V. The temperature coefficient is approximately 20ppm/°C. The adjustable pin allows fine-tuning to exactly 2.500V using a trimmer potentiometer.
How to use the adjust pin on LM336?
Connect a 10kΩ trimmer between the adjust pin and either the cathode or anode. Adjusting this trimmer shifts the output voltage by approximately ±30mV. Use this for initial calibration. For fixed applications, the adjust pin can be left floating.
What biasing does LM336 need?
LM336 is a shunt (2-terminal) reference. Connect a resistor from the positive supply to the cathode: R = (Vsupply - 2.5V) / (Iload + Iref), where Iref should be 0.4-10mA. For a 5V supply with 1mA reference current, use approximately 2.5kΩ.
How does LM336 compare to LM385?
Both are 2.5V shunt references. LM336 offers an adjust pin for fine-tuning while LM385 has fixed output only. LM385 comes in smaller SOT-23, while LM336 is TO-92. LM336B is ±1% while LM385B is ±1.5%. Choose LM336 when trimming is needed.
