ISL9011IRKCZ-T

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

The ISL9011IRKCZ-T is a dual low-dropout (LDO) linear voltage regulator manufactured by Intersil, now part of Renesas. It features two independent channels with fixed output voltages of 2.85V on both Channel 1 and Channel 2. The device supports an input voltage range from 2.3V to 6.5V, with a maximum absolute input voltage of 7.1V. Channel 1 provides a maximum output current of 150mA, while Channel 2 delivers up to 300mA. The quiescent current is typically 45µA when both LDOs are active. The unit operates within a temperature range of -40°C to +85°C and utilizes a DFN-10 package.

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

Verify the specific suffix IRKCZ-T against official Renesas documentation to confirm pinout compatibility and thermal characteristics. Ensure that the fixed output voltage configuration matches the target design requirements, as alternative suffixes may provide different voltage combinations or packaging options. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.

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

Select this component when a dual-output LDO with asymmetric current capabilities is required. Channel 2's higher 300mA capacity suits load-heavy circuits, while Channel 1's 150mA output serves moderate loads. Consider the 1µF to 10µF output capacitor stability window for layout design. The low quiescent current makes it suitable for battery-operated applications where standby power conservation is critical.
