ISL9000IRKCZ-T

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

The ISL9000IRKCZ-T is a dual low-dropout (LDO) linear voltage regulator from the Intersil ISL9000A series, manufactured by Renesas. It provides two independent fixed output voltages of 3.3V each with a total output current capability of 3A. The device operates within an input voltage range of 2.3V to 6.5V and features very high power supply rejection ratio (PSRR) and low noise characteristics suitable for sensitive analog circuits. It utilizes a DFN-10 package and supports operation temperatures from -40°C to +85°C.

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

Verify the specific suffix 'IRKCZ' against official Renesas documentation to confirm pinout compatibility and thermal specifications. Confirm RoHS compliance status through the manufacturer's environmental declaration. Check for End-of-Life (EOL) notices or Last-Time-Buy notifications as older Intersil parts may have limited availability.

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

Select this component when dual isolated rails are required from a single input source. Ensure the load current does not exceed 3A combined. Verify that the output capacitance falls within the stable range of 1µF to 10µF with ESR up to 200mΩ. Consider the DFN-10 package size constraints during PCB layout.
