Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance as per manufacturer standards. Confirm the 'ADJ' designation matches the required adjustable output voltage range of 3.8 V to 5.2 V. Ensure the WSON-10 package footprint aligns with the PCB layout requirements. Cross-reference the datasheet for thermal pad connection guidelines to ensure proper heat dissipation during operation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an inductor-less boost solution is required for noise-sensitive applications. It is appropriate for systems powered by single-cell lithium-ion or alkaline batteries where input voltages vary between 2.7 V and 5.6 V. Consider the 120 mA output limit and 1.7 MHz switching frequency for EMI management. Compare against fixed-output variants if the application does not require adjustable voltage settings.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2750 series of switched-capacitor regulators designed for space-constrained portable electronics. Unlike traditional inductive DC-DC converters, it uses capacitors for energy transfer, reducing component size. The series includes both fixed and adjustable output versions, catering to diverse voltage requirements in mobile and handheld devices.
