ISL9011AIRNNZ

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

The ISL9011AIRNNZ is a dual low-dropout (LDO) linear regulator manufactured by Renesas Electronics Corporation. It features two independent output channels with fixed voltage options, including 2.8V and 3.3V. The device supports an input voltage range from 2.3V to 6.5V. Channel 1 provides a maximum output current of 150mA, while Channel 2 delivers up to 300mA. Key electrical specifications include a typical dropout voltage of 250mV at 300mA, a noise level of 30μVRMS within the 10Hz to 100kHz bandwidth, and an output voltage accuracy of ±1.8%. The quiescent current is typically 40µA.

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

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance and lead-free status prior to integration. Check for End-of-Life (EOL) notices or Product Change Notifications (PCN) as availability may be limited. Ensure storage conditions meet Moisture Sensitivity Level (MSL) requirements to prevent package damage during soldering.

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

Select this component when designing circuits that require two distinct fixed voltages from a single LDO package. Verify that the required output currents do not exceed 150mA for the first channel and 300mA for the second. Ensure the input voltage remains within the 2.3V to 6.5V operational range. Consider the thermal dissipation capabilities of the 10-DFN package based on the expected load and ambient temperature.

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

This part belongs to the ISL9011A series of dual LDO regulators. It is designed for space-constrained applications due to its compact 10-lead DFN (3.0mm x 3.0mm) package. The series emphasizes low standby current and high PSRR, making it suitable for modern portable electronics where battery life and signal integrity are critical design parameters.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

Consult official Renesas documentation for qualified pin-to-pin replacements. Verify that any substitute component matches the 10-DFN footprint and maintains equivalent electrical characteristics, including output current ratings and noise specifications.
