ISL9000AIRPLZ-T

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

The ISL9000AIRPLZ-T is a dual-output low-dropout linear regulator manufactured by Renesas Electronics. It features two fixed output channels providing 1.85V and 2.9V, each capable of delivering up to 300mA. The device utilizes a 10-lead DFN (3x3mm) package with an exposed pad for thermal management. It operates within an input voltage range of 2.3V to 6.5V and supports junction temperatures from -40°C to +85°C. Key electrical characteristics include a maximum dropout voltage of 0.4V at 300mA load and a quiescent current of 32µA.

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

This component is officially classified as obsolete and no longer in active production by the manufacturer. Sourcing should focus on verified surplus distributors or authorized secondary market suppliers. Buyers must validate part authenticity through serial number checks and datasheet cross-referencing. Availability is limited to existing stock; continuous supply cannot be guaranteed. Verify RoHS compliance status prior to integration into new designs.

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

Select this component only if the specific 1.85V and 2.9V fixed outputs align with system requirements. The 300mA per channel limit suits low-power applications rather than high-current loads. Consider the 10-DFN package constraints for PCB layout and thermal dissipation. Due to its obsolete status, ensure long-term availability risks are acceptable for the intended product lifecycle.
