Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific ordering suffix 'X' indicates the tape and reel packaging configuration as documented in official component lists. Confirm that the 'NOPB' designation ensures compliance with RoHS standards and absence of lead-based materials. Cross-reference the full part number against manufacturer databases to ensure availability of the correct package variant.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when space constraints require a small SOT-23 package for low-current applications. It is suitable for designs requiring input voltages up to 42V with output currents not exceeding 0.3A. Consider the fixed 1.2MHz frequency for minimizing passive component size while maintaining efficiency.

Voltage Regulators - DC DC Switching Regulators Part Context

This regulator belongs to the SIMPLE SWITCHER family, designed for ease of use with minimal external components. It complements higher-current variants like the LMR14206 by offering a smaller solution for light loads. The SOT-23 form factor distinguishes it from larger module packages found in other series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LMR14203XMK/NOPB serves as a direct equivalent regarding function and pinout. Verify compatibility with LMR62014 if slightly different current or frequency characteristics are acceptable.
