ISL9011AIRKKZ-T

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

The ISL9011AIRKKZ-T is a dual low-dropout (LDO) voltage regulator manufactured by Renesas Electronics. It features two independent channels with fixed output voltages of 2.85V and 2.85V. 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. The quiescent current is typically 45µA with both LDOs enabled. The unit operates within a temperature range of -40°C to +85°C and is housed in a 10-lead DFN package measuring 3mm x 3mm.

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

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm the exact output voltage combination matches the required system design, as variations exist within the ISL9011 family. Check RoHS compliance status and lead-free plating specifications against current manufacturing standards. Ensure the 10-DFN footprint dimensions align with the PCB layout constraints.

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

Select this component when dual independent outputs are necessary within a compact surface-mount form factor. Consider the 150mA and 300mA current capabilities to ensure adequate headroom for load requirements. Evaluate the dropout voltage characteristics at maximum load currents to maintain regulation under varying input conditions. Verify that the operating temperature range meets the environmental demands of the target application.
