Claim 1
Independent Claim
134 words
A DIRECT-CURRENT LOW VOLTAGE REGULATOR FOR PROVIDING A COMPENSATED OUTPUT VOLTAGE, FROM A SOURCE OF UNREGULATED DIRECT-CURRENT VOLTAGE, COMPRISING: (A) A TRANSISTOR HAVING EMITTER, BASE AND COLLECTOR ELECTRODES; (B) IMPEDANCE MEANS CONNECTED FROM SAID EMITTER ELECTRODE TO A FIRST TERMINAL OF SAID SOURCE; (C) IMPEDANCE MEANS RESPECTIVELY CONNECTING SAID BASE AND COLLECTOR ELECTRODE TO A SECOND TERMINAL OF SAID SOURCE, SAID LAST-NAMED IMPEDANCE MEANS HAVING VALUES OF IMPEDANCE RELATIVELY HIGHER THAN THAT OF THE FIRST-NAMED IMPEDANCE MEANS AND BEING ARRANGED TO PROVIDE A BIAS OF SAID TRANSISTOR NEAR THER ORIGIN OF ITS COLLECTOR SATURATION CHARACTERISTIC; (D) WHEREBY THE COLLECTOR-EMITTER VOLTAGE OF SAID TRANSISTOR VARIES INVERSELY WITH CHANGES IN THE VOLTAGE OF SAID SOURCE; AND (E) STABILIZED OUTPUT VOLTAGE TERMINAL MEANS RESPECTIVELY CONNECTED TO SAID COLLECTOR ELECTRODE AND TO SAID FIRST TERMINAL OF SAID SOURCE.
