ISL9011AIRKFZ-T

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

The ISL9011AIRKFZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It features two independent output channels with fixed voltages of 2.85V 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 (10Hz to 100kHz), and a power supply rejection ratio (PSRR) ranging from 70dB to 40dB across 1kHz to 100kHz. The unit operates within a temperature range of -40°C to +85°C and is housed in a 10-lead DFN package.

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

Verify the specific suffix 'KFZ' against official Renesas documentation to confirm exact output voltage combinations and tape-and-reel packaging details. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Ensure compatibility with existing PCB footprints and thermal management strategies. Check for obsolescence notices or last-time buy notifications as this component series may have limited availability.

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

Select this component when dual isolated LDOs are required in a compact form factor. Ensure the input voltage remains within the 2.3V to 6.5V range under all operating conditions. Verify that the load currents do not exceed 150mA for the first channel and 300mA for the second. Consider the thermal dissipation capabilities of the 10-DFN package relative to the expected power loss. Validate that the output capacitance values fall within the stability range specified in the datasheet.
