ISL9011AIRNFZ-T

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

The ISL9011AIRNFZ-T is a dual low-dropout (LDO) linear regulator manufactured by Renesas Electronics Corporation. It features two independent output channels capable of sourcing 150mA and 300mA respectively. The device operates with an input voltage range of 2.3V to 6.5V and provides fixed output voltages, such as 2.5V and 3.3V. Key electrical specifications include a typical dropout voltage of 250mV at 300mA, a noise level of 30μVRMS from 10Hz to 100kHz, and a power supply rejection ratio (PSRR) ranging from 70dB to 40dB between 1kHz and 100kHz. The unit is housed in a 10-DFN (3x3mm) package.

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

Verify the specific suffix configuration against the manufacturer's official datasheet to ensure compatibility with required output voltages and package variants. Confirm that the component status aligns with long-term availability requirements, as certain versions may be discontinued or subject to obsolescence notices. Cross-reference the ordering part number with authorized distributors to validate authenticity and traceability before finalizing procurement decisions.

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

Select this component when a compact dual-output solution is required for space-constrained designs. Ensure the application demands the specific current ratings of 150mA and 300mA without exceeding thermal limits within the DFN package. Verify that the input voltage remains within the 2.3V to 6.5V range and that the load capacitance falls between 1µF and 10µF for stability. Consider the low standby current if battery life is a critical design parameter.
