ISL9000IRCJZ

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

The ISL9000IRCJZ is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It provides two independent positive fixed outputs, typically configured for 1.8V and 2.8V rails, each capable of sourcing up to 300mA. The device operates with an input voltage range from 2.3V to 6.5V. Key electrical characteristics include a maximum dropout voltage of 0.4V at full load and a quiescent current of approximately 32µA. It features high power supply rejection ratio (PSRR) and integrates individual power-on-reset functions for each output channel within a compact 10-lead DFN package.

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

Verify the exact suffix configuration against official Renesas documentation, as suffixes determine specific output voltages and thermal grades. Confirm component availability status, as this series may be subject to discontinuation notices. Ensure compliance with RoHS directives and check moisture sensitivity levels for proper handling during assembly processes.

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

Select this component when designing circuits that require two distinct fixed voltage outputs from a single regulator IC. Consider the 300mA current limit per channel to ensure adequate headroom for peak loads. Evaluate the input voltage range against the system's supply source to maintain optimal dropout performance. Verify package compatibility with the PCB footprint and thermal requirements.

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

This part belongs to the ISL9000A family of dual LDO regulators designed for high-performance analog and mixed-signal applications.
