Power supply

Examples of power supply circuits for MCU, memory and operational amplifiers / comparators

Circuit Description

Example of Power supply Block Diagram

Operational amplifiers TC75S67TU used for high-precision measuring at the sensor inputs must have a stable power supply to achieve the low-noise performance. In order to make the power supply more stable, it is recommended that the power supply of the op-amp and control MCU must be isolated from the power supply of other electronic circuits. The LDO-regulator's TCR3UG Series enables high-precision power supplies with low current consumption. TCR3UG series offers a lineup of 0.1V steps of output voltage. Select the optimum output voltage according to the specifications of the power supply, sensors, and ADCs in the blood glucose meter system.

Examples of typical recommended products are listed below, and also provide a link to the online distributor inventory search page to buy the product.

Toshiba LDO regulators feature low noise, stable output voltage, low power consumption, and small packages. We offer various products to meet high-performance needs while satisfying local regulations.
