ISL9000AIRCJZ is listed in the Voltage Regulators - Linear, Low Drop Out (LDO) Regulators range at ChipApex. The manufacturer field lists Renesas Electronics Corporation. Its product description is IC REG LINEAR 1.8V/2.8V 10DFN. Review the specifications below when checking this part for your BOM.
The ISL9000AIRJCZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two fixed output voltages of 1.8V and 2.8V, each capable of sourcing up to 300mA. The device operates with an input voltage range from 2.3V to 6.5V and features a maximum dropout voltage of 0.4V at full load. Key electrical specifications include a quiescent current of 32µA and power supply rejection ratios ranging from 90dB to 50dB across frequencies of 1kHz to 100kHz. It is housed in a 10-DFN (3x3mm) package with a bare pad and supports an operating temperature range of -40°C to +85°C.
Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm package integrity and pin alignment due to the small DFN form factor. Check for RoHS compliance documentation if required for specific regulatory standards. Ensure replacement strategies are evaluated given the discontinuation status.
Select this component when dual independent LDO outputs are required in a compact footprint. It is suitable for designs prioritizing low noise and high PSRR over adjustable voltage flexibility. Consider the fixed 1.8V and 2.8V outputs against system rail requirements. Evaluate the 300mA current limit against peak load demands to ensure adequate headroom.
This device belongs to the ISL9000A series of high-performance dual LDOs. It shares architectural similarities with single-output variants like the ISL9001A but offers dual-channel capability. The series is designed for portable electronics where space and power efficiency are critical constraints.
Public confirmed substitute part numbers are not available in the provided data. Due to the obsolete status, direct replacements should be sourced from official Renesas cross-reference tools or verified distributor databases.
