Micropower supply
The circuit design incorporates a CA3440 BiMOS operational amplifier, known for its low power consumption and high performance, making it suitable for battery-operated devices. The CA3086 transistor array complements the op-amp by providing multiple transistor outputs in a compact form factor, enhancing the circuit's versatility and efficiency.
The no-load current of 1.5 µA indicates a very low power draw when the circuit is not actively driving a load, which is beneficial in applications where power efficiency is critical. When a load is applied, the circuit can handle currents up to 200 µA without significant degradation in output voltage regulation. The ability to maintain output voltage regulation within 0.05% under varying load conditions demonstrates the circuit's reliability and stability, which is essential for precision applications.
This circuit can be employed in various applications, including signal conditioning, data acquisition systems, and low-power sensor interfaces, where maintaining a stable output voltage under different load conditions is crucial. The combination of the CA3440 and CA3086 allows for a compact design that does not compromise on performance, making it an excellent choice for modern electronic applications.The circuit uses a CA3440 BiMOS op amp and CA3086 transistor array. The no-load current from 5-volt supply is 1.5 µ A.
Load current can go as high as 200 µ and still maintain output voltage regulation within 0.05%.
