Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments, as National Semiconductor was acquired. Confirm the suffix NOPB indicates lead-free and RoHS compliance. Ensure the WSON-10 package type matches the design requirements. Cross-reference the specific part number against official Texas Instruments documentation to confirm availability and datasheet accuracy before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a low-noise, inductorless boost solution is required for space-constrained designs. The adjustable output allows flexibility for various load requirements within the 3.8 V to 5.2 V range. Consider the 1.7 MHz switching frequency for minimizing passive component size. Evaluate the 120 mA output current limit against peak load demands to ensure adequate performance margins.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2750 series of switched-capacitor regulators. It is distinct from inductive boost converters due to its capacitor-based energy transfer mechanism. The SD package variant denotes a small outline no-leads configuration suitable for surface-mount assembly. The ADJ suffix specifies the adjustable output version, differentiating it from fixed-output variants in the same family.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult Texas Instruments documentation for direct pin-compatible or functionally equivalent alternatives within the LM2750 series or TPS61xxx family. Verify that any substitute maintains the WSON-10 footprint and meets the 1.7 MHz switching frequency requirement. Ensure thermal and electrical specifications align with the original design constraints.
