ISL9000AIRFJZ-T

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

The ISL9000AIRFJZ-T is a dual-channel low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent positive fixed-output LDOs within a compact 10-lead VFDFN package measuring 3.00 x 3.00 mm with a height of 0.88 mm. The device supports an input voltage range from 2.3 V to 6.5 V and delivers up to 300 mA per channel. Fixed output voltages are available in 2.5 V and 2.8 V configurations. Key electrical parameters include a maximum dropout voltage of 400 mV at 300 mA, a typical quiescent current of 42 µA when both channels are active, and a maximum static current of 52 µA.

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

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm specific suffix designations match required output voltages and packaging formats. Check RoHS compliance status and moisture sensitivity levels prior to assembly planning. Ensure ESD handling protocols are followed during storage and installation to maintain device integrity.

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

Select this component when dual isolated rails are needed from a single input source within a small footprint. Consider the 2.5 V and 2.8 V options based on downstream logic requirements. Evaluate the 400 mV dropout limit against minimum input voltage conditions. Verify that external capacitor values fall within the stable range of 1 µF to 10 µF ceramic types to ensure proper loop stability.
