A voltage-regulator multilayer device based on teh conjugated polymer PAN (poly(5-amino-I-naphthol)) sandwiched between silver and tin oxide electrodes is reported. It is shwon that after breakdown at Vcrit the devices is self-regulatory, maintaining an approximately constant potential difference Vstab between the tin oxide and silver electrodes; Vcrit and Vstab depend on the polymer film thickness. The current–voltage characteristic is compared with that of another voltage regulator, the Zener diode.
