Figure 1 shows the general application circuitof three-terminal adjustable positive output integrated voltage regulator circuit ( adjustable negative output voltage regulator has a similar circuit). In the circuit, R1 and RP form the resistor network with adjustable output. in order to makebias current and the tube's leakage currentbe absorbed, R1 is set in the range of 120 ~ 240Ω .The discharge currentflowing throughR1 is 5 ~ 10mA. The input capacitor C1 is used to suppress the ripple voltage. The output capacitor C is used to eliminate vibration andbuffer the impact of load to guarantee the stability of the circuit operation.
