A voltage regulating integrated circuit having high stability and low power consumption features

摘要

A voltage regulating integrated circuit having high stability and low power consumption features, being of a type adapted to produce on an output (E7) a predetermined stable voltage value (Vref) while incorporating wide tolerance internal resistances (R1,R2,R3), is distinctive in that it comprises additional resistances (R4,R5), respectively connected between the base (B1,B2) and the emitter (E1,E3) of predetermined transistors (T1,T3), to compensate for variations in the base-to-emitter voltage drops of such transistors (T1,T5) when biased by currents dependent on the internal resistance values.
