ISL80103IR25Z-TK

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The ISL80103IR25Z-TK is a high-performance, low-voltage, single-output linear regulator (LDO) manufactured by Intersil. It delivers a fixed 2.5V output with a maximum continuous current of 3A. The device operates from an input voltage range of 2.2V to 6V and features a typical dropout voltage of 120mV at full load. Constructed using submicron BiCMOS technology, it offers superior transient response and low quiescent current compared to bipolar alternatives. The component is housed in a compact DFN-10 package.

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

Verify the suffix 'TK' indicates tape-and-reel packaging when sourcing. Confirm the manufacturer source is Intersil or Renesas Electronics. Ensure the part number matches the fixed 2.5V output variant rather than the adjustable version. Check RoHS compliance status as required by project specifications.

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

Select this component for applications requiring stable 2.5V rails with high current demands up to 3A. It is suitable where low noise and fast transient response are critical. Consider the DFN-10 package size for space-constrained designs. Verify input voltage stays within the 2.2V to 6V operational range.

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

This part belongs to the ISL80103 series of high-performance linear regulators. It shares the same core architecture and package as other variants in the family, differing primarily in output voltage configuration. The series is designed for low-voltage, high-current applications requiring efficient power management.

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

The ISL80103IRAJZ is the adjustable voltage variant of the same series. While electrically similar, it requires external resistors to set the output voltage. Direct replacement depends on whether a fixed 2.5V rail is acceptable or if programmability is needed.
