VOLTAGE REGULATOR COLD CATHODE - GLOW DISCHARGE

GLASS BULB SMALL SHELL OCTAL 6-PIN BASE
THE 0A3/VR75, OB3/VR90, 0C3/VR105, AND 0D3/VR150 ARE COLD-CATHODE, GLOW-DISCHARGE. TUBES. THEY ARE INTENDED FOR USE AS VOLTAGE REGULATORS IN APPLICATIONS WHERE IT IS NECESSARY TO MAINTAIN A CONSTANT DC OUTPUT VOLTAGE ACROSS A LOAD, INDEPENDENT OF LOAD CURRENT AND MODERATE LINE-VOLTAGE VARIATIONS. LIKE OTHER GLOW-DISCHARGE TUBES, THEY MAY ALSO BE USED AS RELAXATION OSCILLATORS, AND FOR SPARK-OVER PROTECTION.
