The ZN423 is a monolithic integrated circuit using the energy bandgap voltage of a base-emitter junction to produce a precise, stable, reference source of 1.26V. This is derived via an external dropping resistor for supply voltages of 1.5V upwards. The temperature coefficient of the ZN423, unlike conventional Zener diodes, remains constant with reference current. the noise figure associated with breakdown mechanisms is also considerably reduced.
