ISL9000AIRCJZ-T

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

The ISL9000AIRCJZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It provides two independent fixed output voltages of 1.8V and 2.8V, each capable of sourcing up to 300mA. The device operates within an input voltage range of 2.3V to 6.5V and features a maximum dropout voltage of 0.4V at 300mA load. It utilizes a 10-lead DFN (3x3mm) package with exposed pad for surface mount installation. The unit 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 as the part is marked obsolete. Confirm package integrity and lead condition upon receipt. Check RoHS compliance documentation against current environmental regulations. Ensure storage conditions meet moisture sensitivity level requirements before soldering. Validate datasheet revisions match the specific manufacturing batch date code.

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

Select this component when dual isolated LDO outputs are required in a compact footprint. The 1.8V and 2.8V fixed outputs suit digital logic and analog interfaces. Consider the 300mA per rail limit for load requirements. The DFN-10 package offers thermal advantages for space-constrained designs. Verify input voltage stability remains above the minimum threshold during operation.

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

This device belongs to the ISL9000A series of high-performance dual LDO regulators. It shares architectural similarities with single-output variants like the ISL9001A but provides dual channels. The series emphasizes low noise and high PSRR for sensitive analog applications. Renesas acquired Intersil, which originally developed this product line. The component integrates standard PMIC protection features for robust system reliability.
