This assumes a zener has 20PPM/°C maximum drift and about 10 times lower noise than the regulator. In the application shown below, regulator #2 to “N” will track regulator #1 to within ±24mV initially, and to ±60mV over all load, line, and temperature conditions. If any regulator output is shorted to ground, all other outputs will drop to -2V. Load regulation of regulators 2 to “N” will be improved by VOUT / 1.25V compared to a standard regulator, so regulator #1 should be the one which has the lowest load current.
