Error-Amplifier in Regulated-Power Supplies
The CA3130 is an ideal choice for error-amplifier service in
regulated power supplies since it can function as an error-
amplifier when the regulated output voltage is required to
approach zero. Figure 13 shows the schematic diagram of a
40mA power supply capable of providing regulated output
voltage by continuous adjustment over the range from 0V to
13V. Q3 and Q4 in lC2 (a CA3086 transistor-array lC)
function as zeners to provide supply-voltage for the CA3130
comparator (IC1). Q1, Q2, and Q5 in IC2 are configured as a
low impedance, temperature-compensated source of
adjustable reference voltage for the error amplifier.
Transistors Q1, Q2, Q3, and Q4 in lC3 (another CA3086
transistor-array lC) are connected in parallel as the series-
pass element. Transistor Q5 in lC3 functions as a current-
limiting device by diverting base drive from the series-pass
transistors, in accordance with the adjustment of resistor R2.
Figure 14 contains the schematic diagram of a regulated
power-supply capable of providing regulated output voltage
by continuous adjustment over the range from 0.1V to 50V
and currents up to 1A. The error amplifier (lC1) and circuitry
associated with lC2 function as previously described,
although the output of lC1 is boosted by a discrete transistor
(Q4) to provide adequate base drive for the Darlington-
connected series-pass transistors Q1, Q2. Transistor Q3
functions in the previously described current-limiting circuit.
Multivibrators
The exceptionally high input resistance presented by the
CA3130 is an attractive feature for multivibrator circuit design
because it permits the use of timing circuits with high R/C
ratios. The circuit diagram of a pulse generator (astable
multivibrator), with provisions for independent control of the
“on” and “off” periods, is shown in Figure 15. Resistors R1
and R2 are used to bias the CA3130 to the mid-point of the
supply-voltage and R3 is the feedback resistor. The pulse
repetition rate is selected by positioning S1 to the desired
position and the rate remains essentially constant when the
resistors which determine “on-period” and “off-period” are
adjusted.
Function Generator
Figure 16 contains a schematic diagram of a function
generator using the CA3130 in the integrator and threshold
detector functions. This circuit generates a triangular or
square-wave output that can be swept over a 1,000,000:1
range (0.1Hz to 100kHz) by means of a single control, R1. A
voltage-control input is also available for remote sweep-
control.
