Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature grade (0°C to +70°C) rather than industrial ranges. Confirm the package type matches the required SOIC-8 footprint. Check RoHS compliance status as '+T' variants may differ from standard tube packaging. Ensure the source document explicitly lists this part number to avoid confusion with obsolete equivalents like ICL7660ESA.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits that require simple DC-DC conversion without inductors. It is suitable for applications needing moderate current levels up to 20 mA. Consider the 10 kHz switching frequency for noise-sensitive designs. Verify that the external capacitor requirements align with the board space constraints.
