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

Verify the specific suffix 'TK' against official Intersil documentation to confirm tape-and-reel packaging details. Ensure the 1.8V fixed output variant matches the design requirement. Confirm RoHS compliance status as indicated in the datasheet. Cross-reference the DFN-10 package dimensions with mechanical drawings for PCB layout accuracy.

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

Select this component when a fixed 1.8V output is required with up to 2A load capability. It is suitable for applications where input voltages range between 2.2V and 6V. Consider the DFN-10 package size for space-constrained designs. Verify thermal requirements for operation up to 125°C junction temperature.

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

This part belongs to the ISL80102/ISL80103 series of high-performance linear regulators manufactured by Intersil (now Renesas). The series includes adjustable and fixed output versions with 2A and 3A current ratings. These regulators are designed for modern low-voltage digital systems requiring clean power delivery.

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

Check for direct substitutes within the ISL80102 family with different output voltages if 1.8V is not strictly required. Verify pin compatibility with other 2A LDOs in the same package before substitution.
