ISL9011IRKKZ-T

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

The ISL9011IRKKZ-T is a dual low-dropout (LDO) voltage regulator manufactured by Renesas Electronics, formerly Intersil. It features two independent channels with fixed output voltages of 2.85V each. The device supports a maximum input voltage of 6.5V and operates within an extended temperature range of -40°C to +85°C. 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 component 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 manufacturer designation as Renesas Electronics, noting the historical Intersil branding. Ensure the part number matches the exact fixed output voltage variant required for the design. Check for RoHS compliance status and moisture sensitivity level requirements during storage and handling.

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 main logic loads, while Channel 1's 150mA fits peripheral circuits. The fixed 2.85V outputs eliminate external resistor networks. Consider the 10-DFN footprint constraints and thermal dissipation needs under maximum load conditions.
