ISL9000AIRNCZ

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

The ISL9000AIRNCZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics, formerly Intersil. It provides two fixed output voltages of 1.8V and 3.3V with a maximum output current of 300mA per channel. The device operates within an input voltage range of 2.3V to 6.5V and features a typical quiescent current of 32µA. It utilizes a 10-lead DFN (3x3mm) package and supports an operating temperature range from -40°C to +85°C.

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

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS compliance and lead-free soldering requirements against specific project standards. Validate package dimensions and pinout compatibility during PCB layout finalization. Review manufacturer notices for any product discontinuance announcements affecting long-term supply stability.

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

Select this component when dual isolated outputs are required within a small footprint. Ensure input voltage remains above the dropout threshold for both 1.8V and 3.3V rails under maximum load conditions. Verify that external capacitor ESR values fall within the specified stability range to prevent oscillation. Consider thermal dissipation capabilities given the limited surface area of the DFN-10 package.

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

This part belongs to the ISL9000A series of dual LDO regulators designed for low-noise performance. It shares architectural similarities with other members like the ISL9001 single-channel variant but offers dual functionality. The series targets applications demanding high PSRR and low quiescent current in space-constrained environments.
