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

Verify the specific suffix against official ROHM documentation to confirm pinout compatibility and electrical tolerances. Confirm RoHS compliance status via the manufacturer's latest datasheet. Ensure the procurement channel sources genuine components to avoid counterfeit risks associated with legacy linear regulators. Cross-reference the part number with authorized distributors to validate current availability and lifecycle status before finalizing orders.

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

Select this component when a fixed 8 V output at 1 A is required using through-hole technology. The TO-220CP-3 package facilitates effective thermal management for higher power dissipation scenarios compared to surface-mount alternatives. Consider the input voltage headroom requirements relative to the 10.5 V minimum specification. Evaluate thermal resistance parameters if operating near the upper limits of the specified temperature range.

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