ISL9011AIRBCZ-T

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

The ISL9011AIRBCZ-T is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It integrates two independent LDO channels within a single 10-lead, 3mm x 3mm DFN package. Channel 1 provides a fixed output voltage of 1.5V with a maximum continuous current capability of 150mA. Channel 2 delivers a fixed output voltage of 1.8V with a maximum continuous current capability of 300mA. The device operates from an input supply voltage ranging between 2.3V and 6.5V. It features a typical quiescent current of 45µA when both regulators are active and supports ceramic output capacitors in the range of 1µF to 10µF.

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

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and Pb-free plus anneal specifications prior to integration. Ensure proper handling procedures are followed due to electrostatic discharge sensitivity. Validate that the specific voltage combination matches the design requirements before finalizing procurement orders.

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

Select this component for applications requiring dual regulated rails from a single source. Verify that the required output voltages match the fixed 1.5V and 1.8V configuration. Ensure the load current does not exceed 150mA for the first channel or 300mA for the second channel. Confirm compatibility with the 2.3V to 6.5V input voltage range and verify space constraints fit the 10-lead DFN package dimensions.
