ISL9000IRCCZ-T

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

The ISL9000IRCCZ-T is a dual-output low-dropout (LDO) linear voltage regulator manufactured by Renesas Electronics Corporation. It provides fixed output voltages of 1.8V and 3.3V, each capable of sourcing up to 300mA of output current. The device operates with an input voltage range from 2.3V to 6.5V and features a typical dropout voltage of 200mV at 300mA load. It includes built-in protection mechanisms such as overcurrent limiting, thermal shutdown, and undervoltage lockout. The component is housed in a compact 10-DFN (3x3mm) package with an exposed pad for enhanced thermal performance.

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

Verify the exact suffix configuration against the manufacturer's datasheet to ensure correct output voltage combinations. Confirm RoHS compliance status and lead times through authorized distributors, as availability may vary. Check for obsolescence notices or product change notifications prior to final design approval.

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

Select this component when dual fixed outputs are required without external resistors. Ensure the input voltage remains within the specified 2.3V to 6.5V range under all operating conditions. Consider thermal dissipation requirements based on the load current and ambient temperature, as the DFN package relies on PCB copper for heat spreading.
