ISL9011IRLLZ-T

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

The ISL9011IRLLZ-T is a dual low-dropout linear regulator manufactured by Renesas Electronics Corporation. It provides two independent fixed output voltages: Channel 1 (VO1) at 2.9V with a maximum continuous current of 150mA, and Channel 2 (VO2) at 2.9V with a maximum continuous current of 300mA. The device operates within an input voltage range of 2.3V to 6.5V and maintains a typical quiescent current of 45µA when both channels are active. It features ±1.8% regulation accuracy over the full operating temperature range of -40°C to +85°C.

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 check for specific manufacturing lot codes if required for quality assurance. Ensure proper handling procedures are followed due to moisture sensitivity classification. Review datasheet specifications against application requirements before finalizing procurement decisions.

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

Select this component for applications requiring dual independent voltage rails from a single package. Verify that the required output voltages match available factory-trimmed options. Ensure load currents do not exceed 150mA for Channel 1 or 300mA for Channel 2. Consider the 10-lead DFN package size constraints and thermal dissipation capabilities relative to the PCB layout design.

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

This part belongs to the ISL9011 series of dual LDO regulators designed for portable electronics. It replaces older Intersil designs under the Renesas Electronics Corporation portfolio. The device utilizes a tiny 10-lead 3mm x 3mm Dual Flat No-Lead (DFN) package to minimize board space usage while maintaining high performance characteristics suitable for battery-powered devices.

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

The datasheet explicitly states pin compatibility with Micrel MIC2211. Verify electrical parameters such as dropout voltage and current ratings against the MIC2211 specifications to ensure functional equivalence in existing designs.
