ISL9014AIRLLZ

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

The ISL9014AIRLLZ is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent LDOs, each capable of sourcing up to 300mA of continuous output current. The device provides fixed positive output voltages of 2.9V on both VO1 and VO2 channels. It operates within an input voltage range of 2.3V to 6.5V and maintains high performance with extremely low quiescent current consumption of typically 45µA when both regulators are active. The component features ±1.8% accuracy over all operating conditions.

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

Verify the specific ordering suffix 'LL' confirms the 2.9V/2.9V fixed output configuration before procurement. Confirm RoHS compliance status as the datasheet indicates Pb-free plastic packaged products employ special material sets. Check for any product change notices or end-of-life updates that may affect long-term availability and supply chain stability.

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

Select this component when dual isolated power rails are required in a compact footprint. Ensure the application load does not exceed the 300mA per channel limit. Verify that the input voltage remains within the 2.3V to 6.5V operational range. Consider the thermal resistance characteristics if multiple units operate at high ambient temperatures.
