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

Verify the specific suffix (e.g., -E2) against the manufacturer's current datasheet to confirm RoHS compliance and exact pinout configuration. Ensure the selected variant matches the required thermal dissipation capabilities for the intended application environment. Cross-reference the part number with official ROHM documentation to avoid counterfeit components.

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

Select this component when a fixed 18 V output at up to 500 mA is required in a surface-mount format. Consider the thermal resistance of the TO-252-3 package and ensure adequate heatsinking if the input-output differential voltage results in significant power dissipation. Verify that the minimum input voltage requirement of 21 V aligns with the available supply rails.

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