ISL9000AIRKCZ-T

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

The ISL9000AIRKCZ-T is a dual-channel low dropout linear regulator from the ISL9000A series, manufactured by Renesas Electronics. It integrates two independent 300mA LDOs in a compact 10-lead DFN (3x3mm) package. The device supports an input voltage range of 2.3V to 6.5V with fixed output voltages of 1.8V and 2.85V. Key electrical characteristics include a typical quiescent current of 42µA, a maximum dropout voltage of 0.325V at full load, and a power supply rejection ratio of 90dB at 1kHz. It operates within a temperature range of -40°C to +85°C.

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

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm the specific suffix 'KCZ' matches the required 1.8V/2.85V output configuration and tape-and-reel packaging format. Check for recent product change notifications regarding manufacturing site updates or lead-free compliance status before finalizing procurement orders.

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

Select this component when dual isolated rails are needed from a single input source. Ensure the input voltage remains above the minimum threshold of 2.3V while accounting for dropout requirements. Verify that the external capacitor values fall within the stable range of 1µF to 10µF ceramic capacitors to maintain loop stability under all load conditions.

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

This part belongs to the ISL9000A family of dual LDO regulators designed for space-constrained applications. It succeeds earlier Intersil designs now integrated into the Renesas portfolio. The device shares functional similarities with the ISL9001A but offers dual outputs instead of a single channel, providing greater flexibility for multi-rail power distribution networks.

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

Direct substitutes may include other ISL9000A variants with different fixed output voltages, such as ISL9000AIRKJZ or ISL9000AIRNNZ, provided the voltage levels match the design requirements. Cross-reference pinouts and thermal characteristics to ensure compatibility with existing PCB layouts.
