ZN423 Description
THIS DOCUMENT IS FOR MAINTENANCE PURPOSES ONLY AND IS NOT REMENDED FOR NEW DESIGNS DS2347 - 3.0 ZN423 PRECISION VOLTAGE REFERENCE SOURCE 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...
