Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing circuits that require a compact, high-voltage input step-down solution with adjustable output. It is suitable for space-constrained designs where a thin SOT-23 package is preferred over larger alternatives. Consider the 300 mA current limit and 1.25 MHz switching frequency when determining external inductor and capacitor values for optimal performance and stability.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM284x family of SIMPLE SWITCHER regulators, which includes variants with different current ratings such as 100 mA and 600 mA. These devices share common architectural features but differ in output capabilities and specific package options. The LM2840 specifically targets applications needing moderate current output within a very small footprint.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Compatible substitutes include other LM284x series parts like LM2841 or LM2842, provided the current rating and package type meet design requirements. Verify that alternative components support the same 42 V input range and adjustable output functionality.
