Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the complete part number including the suffix TR for tape and reel packaging configuration. Confirm the operating temperature range matches the specific environmental requirements of the target application. Ensure compatibility with the PCB footprint designated for the SOT-223 package during layout design.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 3.5V output is required with moderate current demands up to 1A. Consider the dropout voltage characteristics relative to the minimum input voltage available in the system. Evaluate the thermal performance based on the expected power dissipation and board copper area for heat spreading.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This regulator belongs to the L4931 series of low-dropout regulators designed for efficiency and stability. The series offers various fixed output voltages to accommodate different logic levels. The CD35 variant specifically targets applications needing a 3.5V supply from higher voltage sources like lithium-ion batteries or unregulated adapters.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that offer similar current ratings and output voltages. Verify that any substitute maintains the same package type and thermal characteristics to avoid redesigning the printed circuit board.
