Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.875V rail is required with moderate current demands up to 600mA. It is appropriate for designs prioritizing small footprint over adjustable output flexibility. Consider thermal performance in dense layouts due to the small package size. Verify that the input voltage source remains within the specified operational limits during all system states.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3677 family of miniature step-down converters designed for ultra-low voltage circuits. The series offers various fixed output voltages to accommodate different logic levels in portable systems. National Semiconductor was acquired by Texas Instruments, which continues production under the TI brand while maintaining the original product specifications and naming conventions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM3677LE-1.8/NOPB: Different package (6-USON vs 5-DSBGA) and output voltage (1.8V vs 1.875V). LM3677TL-1.5/NOPB: Same package but different fixed output voltage (1.5V). LM3677TL-1.2: Same package but different fixed output voltage (1.2V). Verify pinout compatibility and electrical parameters before substitution.
