S1854 is a regulator driver for line operated TV, which are built up of error amplifier transistor, standard voltage zener diode and poly-silicon resistors on monolithic chip.
1. Possible to eliminate the output voltage adjustment of regulator stage in line operated tv, combined with the usual power transistors.
2. High voltage ( Vcgo > 150V )
3. Excellent temperature characteristics of regulated output voltage.
