ISL9011AIRPLZ-T

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

The ISL9011AIRPLZ-T is a dual low-dropout linear regulator from the ISL9011A series, manufactured by Renesas Electronics. It integrates two independent LDO channels within a compact 10-lead 3mm x 3mm DFN package. Channel 1 provides a fixed output voltage of 1.85V with a maximum continuous current capability of 150mA. Channel 2 delivers a fixed output voltage of 2.9V with a maximum continuous current capability of 300mA. The device operates over an input voltage range of 2.3V to 6.5V and supports an ambient operating temperature range of -40°C to +85°C.

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

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and Pb-free plus anneal status. Ensure proper ESD handling procedures are followed during storage and assembly. Validate that the specific ordering suffix matches the required tape and reel packaging configuration.

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

Select this component when a dual-rail power solution is required in a space-constrained design. The fixed 1.85V and 2.9V outputs eliminate external resistor networks. Verify that the load requirements do not exceed the 150mA and 300mA limits for Channels 1 and 2 respectively. Ensure the application benefits from the low noise characteristics provided by the reference bypass pin.
