ISL9011AIRCCZ-T

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

The ISL9011AIRCCZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics. It features two independent channels with fixed output voltages of 2.5V and 1.8V. 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 quiescent current of 45µA, a maximum dropout voltage of 0.2V at 150mA for the first channel, and noise performance of 30µVRMS over the 10Hz to 100kHz bandwidth. The unit operates within a temperature range of -40°C to +85°C and utilizes a 10-lead DFN package.

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

Verify the specific suffix 'CC' against official Renesas documentation to confirm the exact output voltage combination, as suffixes define fixed voltage options. Confirm the '-T' designation indicates tape-and-reel packaging if required for automated assembly. Check component status, as this series may be subject to discontinuation notices. Ensure compatibility with RoHS and REACH regulations for your target market.

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

Select this component when a compact dual LDO solution is needed for space-constrained designs. It is appropriate for applications requiring simultaneous stable rails with different current demands. Consider the 1µF to 10µF output capacitance stability window during layout. Evaluate the thermal dissipation capabilities of the DFN package relative to the expected load currents and ambient operating temperatures.

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

This part belongs to the ISL9011A family of dual LDO regulators originally developed by Intersil before its acquisition by Renesas. The family is characterized by low standby current and high PSRR. Variants in the series differ primarily in output voltage combinations and package types, such as DFN or WLCSP, catering to diverse portable and industrial power management requirements.

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

Cross-reference with other ISL9011 variants like ISL9011AIRKCZ or ISL9011AIRNCZ to match specific voltage outputs. Verify pin-to-pin compatibility and ensure equivalent electrical parameters before substitution.
