MONOLITHIC TEMPERATURE<br />

COMPENSATED ZENER DIODE<br />

Monolithic linear integrated circuit producing<br />

an extremely constant temperature-compensated<br />

voltage, particularly suitable for stabilizing<br />

the tuning voltage in Television and Radio<br />

tuners employing capacitance diodes. This<br />

device is available in a low-cost diode package.<br />
