Working Principle

The LM336BZ-5.0/NOPB is a three-terminal voltage reference. It can provide a stable 5.0 volt output with a temperature coefficient of 500 ppm/°C (typical). It achieves this by using a bandgap reference circuit, which uses the base-emitter voltage of a bipolar junction transistor (BJT) to generate a precise reference voltage.

The LM336BZ-5.0/NOPB has a wide input voltage range of 4.8V to 30V. This voltage is applied to the base of the BJT, which is kept at a constant current by the emitter resistor. The base-emitter voltage of the BJT is then used as a reference voltage that is applied to the output of the circuit. This reference voltage is then compared to a stored voltage value in the circuit and if it is not the same, the circuit adjusts the output to match the reference voltage.

The LM336BZ-5.0/NOPB also has a low offset current of only 1.8μA (typical) and low temperature drift of 300ppm/°C (typical). This ensures that the circuit can maintain a stable 5.0 volt output over a wide temperature range.

The LM336BZ-5.0/NOPB is a versatile component that is perfect for a wide range of applications, including local on-board reference sources, precision current reference sources, battery and power supply monitoring, accurate temperature measurement and process control applications.
