Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official documentation. Datasheets indicate the standard part number as LM828M5X/NOPB with an 'X' suffix for tape-and-reel packaging. Confirm if the requested model without the 'X' corresponds to cut-tape or tube variants. Ensure compatibility with the required output current and voltage inversion specifications for the target circuit design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution for generating negative voltage rails from a single positive source is required. It is suitable for low-power portable electronics where minimizing quiescent current is critical. Verify that the load current does not exceed the 25mA limit and that the input voltage remains within the specified operational range.
